Convert a Unix timestamp to time in JavaScript

Asked 11/5, 2009 at 8:23 Answered 5/2 at 10:39

I am storing time in a MySQL database as a Unix timestamp and that gets sent to some JavaScript code. How would I get just the time out of it?

For example, in HH/MM/SS format.

Just multiply by 1000 since JS timestamps are in milliseconds and PHP delivers in seconds. – Adaxial 1/11, 2017 at 9:50

Here is a very useful link with different date format: timestamp.online/article/… Combine with the multiplication by 1000 and it gets the job done! – Perreault 25/3, 2020 at 11:13

dt=new Date(1234567890 * 1000).toLocaleString(); gives date+time — or use .toLocaleDateString() or .toLocaleTimeString()) – Giblet 17/5, 2022 at 3:41

let unix_timestamp = 1549312452;

// Create a new JavaScript Date object based on the timestamp
// multiplied by 1000 so that the argument is in milliseconds, not seconds
var date = new Date(unix_timestamp * 1000);

// Hours part from the timestamp
var hours = date.getHours();

// Minutes part from the timestamp
var minutes = "0" + date.getMinutes();

// Seconds part from the timestamp
var seconds = "0" + date.getSeconds();

// Will display time in 10:30:23 format
var formattedTime = hours + ':' + minutes.substr(-2) + ':' + seconds.substr(-2);

console.log(formattedTime);

For more information regarding the Date object, please refer to MDN or the ECMAScript 5 specification.

also you could save yourself a couple of processor ticks by avoiding the need for the large multiplication by just appending three 0s: echo "var date = new Date(" . $timestamp . "000);\n"; – Horseback 13/5, 2009 at 4:8

@Horseback multiplications are trivial on modern CPUs - the string concatenation will require a lot more work! – Lignite 19/4, 2011 at 19:59

Concatenation should consist of reading memory and writing memory..how could someone design something that takes something simple such as appending and make it more complicated than multiplaction...ask a child to concatenate and they can..multiplicaion is more difficult...plus memory is laid out to work linearly anyawyas...Can someone provide a reference to the @Horseback comment? – Fanny 6/1, 2012 at 17:8

Actually it will display time in '10:2:2' format, since it does not add an extra 0 before values below 10. – Harper 4/10, 2012 at 14:47

@Harper Then let's get it fixed, shall we? :] See my answer at the bottom. – Cassidy 23/7, 2013 at 10:10

Any way we can extract the day and date and time, like 21 August, 12:11:23 as well? – Bibbie 7/8, 2013 at 13:10

@Cupidvogel , sure, check the reference the OP provided, or any of the other answers, which cover month and date as well. – Scruggs 26/9, 2013 at 15:21

@Fanny - Multiplication involves numbers, concatenation involves strings. Computers handle numbers far more efficiently than strings. When string concatenation is done, there's a lot of memory management going on in the background. (However, if you're already doing a string concatenation anyway, then including a few extra characters in one of the strings might actually be less costly on average than the one processor op it takes to multiply two numbers together.) – Starvation 2/10, 2013 at 21:31

Just a minor thing about concatenation: Using .join() is a lot more efficient. However, this this suggests that concatination is becoming more efficient in some cases. – Reddick 1/8, 2014 at 6:6

@Lignite What suggests that string concatenation takes more memory than number computation? – Terzetto 19/3, 2016 at 11:53

@Stallman number computation is the most fundamental thing that computers do, and they're extremely efficient at it, both in memory and runtime. Brilliand's comment above is relevant, although IMHO the very final part of his comment is completely bogus. – Lignite 19/3, 2016 at 11:59

@Starvation What suggests that string concatenation takes more memory than number computation? I would like to know more about it., is that the property of JS or for all kind of language? – Terzetto 19/3, 2016 at 12:46

@Stallman It's true of all languages (or nearly all, in theory an exotic language could be created that isn't like this - but all the common ones are). A string is stored internally as a pointer to a block of memory where the contents of the string are stored. The pointer itself uses the same amount of memory as most numbers do on the same system, and the memory to store the actual strings is in addition to that. Then when you concatenate the strings, you're most often creating a brand-new string with the combined contents of both strings. – Starvation 21/3, 2016 at 23:32

@Starvation Here is my understandings: You mean that a string may occupies lots of memory since it consists of lots of chars but the number only takes a little memory. Take C for instance, if the system is 64 OS based, the integer takes 4 bytes; nevertheless the strings may take much more than that.(1*N) And in the process of concatenation, the OS requires to allocate additional memory to accommodate the concatenated strings. – Terzetto 22/3, 2016 at 15:37

My timestamp is in UTC format. Any change I need to make here for that? How can I have am/pm? – Dilute 17/10, 2016 at 9:29

@Terzetto It's really a lot more complicated than that. Strings are stored as a stack pointer to an array, the contents of which are stored on the heap (whereas integers are stored directly on the stack). That means that every call to a string also involves a dereferencing operation. Of course, computers do this quite quickly. But each of these strings is also allocated additional memory to allow for mutation, which can balloon the amount of memory required. – Fez 3/11, 2020 at 18:3

I don't know if it will help the discussion, but beware that if you give the Date constructor a number, it knows exactly how to interpret it. But if you give the Date constructor a string, it would have to validate it, as there are dozens of possible string date time constructs that are all equally as valid, so there would be some validation necessary while the number as an input does not require any – Ferino 5/8, 2021 at 17:13

String.substr() is deprecated nowadays. Use slice instead, which can also cover the negative index. – Chaliapin 17/1, 2022 at 11:42

To get only date part: let str = date.toISOString().split('T')[0]; – Relly 16/3, 2022 at 7:45

Please modify the code to use String.substring() instead of String.substr(). It's deprecated. – Frobisher 22/12, 2022 at 6:38

Ironwood answered 21/5, 2011 at 0:44 Comment(4)

for HH/MM/SS just use last three variables and this is time will be in your local time but if you want to get the UTC time just use the getUTC methods. Here's the code. – Ironwood 21/5, 2011 at 0:52

I used this solution but tweaked it so that minutes and seconds would show up as :03 or :09 instead of :3 or :9, like so:

var min = a.getMinutes() < 10 ? '0' + a.getMinutes() : a.getMinutes(); var sec = a.getSeconds() < 10 ? '0' + a.getSeconds() : a.getSeconds();

– Alboin 8/8, 2014 at 16:40

Bug: getMonth() returns a month number between 0 and 11, thus a.getMonth() - 1 is wrong. – Urbannal 27/8, 2014 at 17:41

Don't need a list of month names, javascript has that, even in IE. var month = a.toLocaleDateString(undefined, {month: 'short'}) – Sketchy 29/6, 2021 at 21:58

JavaScript works in milliseconds, so you'll first have to convert the UNIX timestamp from seconds to milliseconds.

var date = new Date(UNIX_Timestamp * 1000);
// Manipulate JavaScript Date object here...

Use:

var s = new Date(1504095567183).toLocaleDateString("en-US")
console.log(s)
// expected output "8/30/2017"

and for time:

var s = new Date(1504095567183).toLocaleTimeString("en-US")
console.log(s)
// expected output "3:19:27 PM"

see Date.prototype.toLocaleDateString()

Modern Solution (for 2020)

In the new world, we should be moving towards the standard Intl JavaScript object, that has a handy DateTimeFormat constructor with .format() method:

function format_time(s) {
  const dtFormat = new Intl.DateTimeFormat('en-GB', {
    timeStyle: 'medium',
    timeZone: 'UTC'
  });
  
  return dtFormat.format(new Date(s * 1e3));
}

console.log( format_time(12345) );  // "03:25:45"

Eternal Solution

But to be 100% compatible with all legacy JavaScript engines, here is the shortest one-liner solution to format seconds as hh:mm:ss:

function format_time(s) {
  return new Date(s * 1e3).toISOString().slice(-13, -5);
}

console.log( format_time(12345) );  // "03:25:45"

Method Date.prototype.toISOString() returns time in simplified extended ISO 8601 format, which is always 24 or 27 characters long (i.e. YYYY-MM-DDTHH:mm:ss.sssZ or ±YYYYYY-MM-DDTHH:mm:ss.sssZ respectively). The timezone is always zero UTC offset.

This solution does not require any third-party libraries and is supported in all browsers and JavaScript engines.

I'm pasting your function in Chrome's console :/ Even in your fiddle it's showing 01:02:00 for me ! Tried on Firefox, same results. Very strange...I'm pretty sure it's because I'm GMT+1 ! – Camaraderie 10/2, 2017 at 8:50

I've offered an edit for your answer that ignores any timezone, so it'll always show the right formatted value ! – Camaraderie 10/2, 2017 at 9:2

@SteveChamaillard Thank you, Steve. You were right, toTimeString was not working well with time zones. Unfortunately your edit was rejected before I saw it. However, I'd suggest to use toISOString instead, since toGMTString is deprecated and may return different results on different platforms. – Hearst 10/2, 2017 at 14:28

Even shorter with ES6: let time = s => new Date(s * 1e3).toISOString().slice(-13, -5) – Capitular 22/5, 2018 at 9:33

I'm partial to Jacob Wright's Date.format() library, which implements JavaScript date formatting in the style of PHP's date() function.

new Date(unix_timestamp * 1000).format('h:i:s')

@Petrillo - sounds like you are in eastern US time zone and the timestamps are UTC. Try removing the .slice(0,19) and I think you will see the timezone of the result is Z (Zulu). – Heidiheidie 20/12, 2019 at 5:55

I'd think about using a library like momentjs.com, that makes this really simple:

Based on a Unix timestamp:

var timestamp = moment.unix(1293683278);
console.log( timestamp.format("HH/mm/ss") );

Based on a MySQL date string:

var now = moment("2010-10-10 12:03:15");
console.log( now.format("HH/mm/ss") );

another advantage of moment.js (or similar libs) would be their support of relative time, for messages like "6 hours ago". – Ostensory 10/2, 2015 at 12:33

moment.js is waaay overkill for such a small thing to do and will affect your performance. Use native methods instead, cf. Dan Alboteanu's answer – Slime 10/3, 2019 at 7:53

In moment you must use unix timestamp:

const dateTimeString = moment.unix(1466760005).format("DD-MM-YYYY HH:mm:ss");

This works with PHP timestamps

var d = 1541415288860;
//var d =val.timestamp;

//NB: use + before variable name
var date = new Date(+d);

console.log(d);
console.log(date.toDateString());
console.log(date.getFullYear());
console.log(date.getMinutes());
console.log(date.getSeconds());
console.log(date.getHours());
console.log(date.toLocaleTimeString());

var d =val.timestamp;
var date=new Date(+d); //NB: use + before variable name

console.log(d);
console.log(date.toDateString());
console.log(date.getFullYear());
console.log(date.getMinutes());
console.log(date.getSeconds());
console.log(date.getHours());
console.log(date.toLocaleTimeString());

Kelbee answered 5/11, 2018 at 13:25 Comment(0)

UNIX timestamp is number of seconds since 00:00:00 UTC on January 1, 1970 (according to Wikipedia).

Argument of Date object in Javascript is number of miliseconds since 00:00:00 UTC on January 1, 1970 (according to W3Schools Javascript documentation).

See code below for example:

    function tm(unix_tm) {
        var dt = new Date(unix_tm*1000);
        document.writeln(dt.getHours() + '/' + dt.getMinutes() + '/' + dt.getSeconds() + ' -- ' + dt + '<br>');

    }

tm(60);
tm(86400);

gives:

1/1/0 -- Thu Jan 01 1970 01:01:00 GMT+0100 (Central European Standard Time)
1/0/0 -- Fri Jan 02 1970 01:00:00 GMT+0100 (Central European Standard Time)

Using Moment.js, you can get time and date like this:

var dateTimeString = moment(1439198499).format("DD-MM-YYYY HH:mm:ss");

And you can get only time using this:

var timeString = moment(1439198499).format("HH:mm:ss");

You can easily convert timestamp to date usign momentJS, you checkout this coderszine.com/convert-timestamp-to-date-using-javascript – Matchboard 8/2, 2018 at 7:3

The problem with the aforementioned solutions is, that if hour, minute or second, has only one digit (i.e. 0-9), the time would be wrong, e.g. it could be 2:3:9, but it should rather be 02:03:09.

According to this page it seems to be a better solution to use Date's "toLocaleTimeString" method.

Gaptoothed answered 1/11, 2011 at 19:11 Comment(2)

for most web solutions, this is the most correct answer, since it uses the client's locale, e.g. 24h vs. 12h am/pm format. For a time string, you would then use: date.toLocaleTimeString() – Malaya 16/6, 2013 at 14:2

Another way - from an ISO 8601 date.

var timestamp = 1293683278;
var date = new Date(timestamp * 1000);
var iso = date.toISOString().match(/(\d{2}:\d{2}:\d{2})/)
alert(iso[1]);

The modern solution that doesn't need a 40 KB library:

Intl.DateTimeFormat is the non-culturally imperialistic way to format a date/time.

// Setup once
var options = {
    //weekday: 'long',
    //month: 'short',
    //year: 'numeric',
    //day: 'numeric',
    hour: 'numeric',
    minute: 'numeric',
    second: 'numeric'
},
intlDate = new Intl.DateTimeFormat( undefined, options );

// Reusable formatter
var timeStamp = 1412743273;
console.log( intlDate.format( new Date( 1000 * timeStamp ) ) );

There are multiple ways to convert unix timestamp to time (HH/MM/SS)

Using new Date() - this is in-built in javascript
moment package - this is a famous node module, but this is going to deprecate.
dayjs package - this is one of the latest and fast growing node module

Using new Date()

const dateTimeStr = new Date(1504052527183).toLocaleString()
const result = (dateTimeStr.split(", ")[1]).split(":").join("/")
console.log(result)

Using moment

const moment = require('moment')
const timestampObj = moment.unix(1504052527183);
const result = timestampObj.format("HH/mm/ss")
console.log(result);

Using day.js

const dayjs = require('dayjs')
const result = dayjs(1504052527183).format("HH/mm/ss")
console.log(result);

you can check the timestamp to date time conversion with an online time conversion tool

Carr answered 5/2, 2022 at 9:37 Comment(0)

Pay attention to the zero problem with some of the answers. For example, the timestamp 1439329773 would be mistakenly converted to 12/08/2015 0:49.

I would suggest on using the following to overcome this issue:

var timestamp = 1439329773; // replace your timestamp
var date = new Date(timestamp * 1000);
var formattedDate = ('0' + date.getDate()).slice(-2) + '/' + ('0' + (date.getMonth() + 1)).slice(-2) + '/' + date.getFullYear() + ' ' + ('0' + date.getHours()).slice(-2) + ':' + ('0' + date.getMinutes()).slice(-2);
console.log(formattedDate);

Now results in:

12/08/2015 00:49

Vichyssoise answered 11/8, 2015 at 22:9 Comment(0)

You can use the following function to convert your timestamp to HH:MM:SS format :

var convertTime = function(timestamp, separator) {
    var pad = function(input) {return input < 10 ? "0" + input : input;};
    var date = timestamp ? new Date(timestamp * 1000) : new Date();
    return [
        pad(date.getHours()),
        pad(date.getMinutes()),
        pad(date.getSeconds())
    ].join(typeof separator !== 'undefined' ?  separator : ':' );
}

Without passing a separator, it uses : as the (default) separator :

time = convertTime(1061351153); // --> OUTPUT = 05:45:53

If you want to use / as a separator, just pass it as the second parameter:

time = convertTime(920535115, '/'); // --> OUTPUT = 09/11/55

Demo

var convertTime = function(timestamp, separator) {
    var pad = function(input) {return input < 10 ? "0" + input : input;};
    var date = timestamp ? new Date(timestamp * 1000) : new Date();
    return [
        pad(date.getHours()),
        pad(date.getMinutes()),
        pad(date.getSeconds())
    ].join(typeof separator !== 'undefined' ?  separator : ':' );
}

document.body.innerHTML = '<pre>' + JSON.stringify({
    920535115 : convertTime(920535115, '/'),
    1061351153 : convertTime(1061351153, ':'),
    1435651350 : convertTime(1435651350, '-'),
    1487938926 : convertTime(1487938926),
    1555135551 : convertTime(1555135551, '.')
}, null, '\t') +  '</pre>';

Shortest

(new Date(ts*1000)+'').slice(16,24)

let ts = 1549312452;
let time = (new Date(ts*1000)+'').slice(16,24);

console.log(time);

Try this :

      new Date(1638525320* 1e3).toISOString()  //2021-12-03T09:55:20.000Z

can you explain how does it work? what is 1e3 and why we multiple it? – Joanejoanie 26/4, 2022 at 12:48

@VasylGutnyk new Date expects time in milliseconds, but we usually hus it in seconds, so we multiply it by 1000. 1e3 is the same as 1000 – Peerless 6/8, 2022 at 9:42

function getDateTime(unixTimeStamp) {

    var d = new Date(unixTimeStamp);
    var h = (d.getHours().toString().length == 1) ? ('0' + d.getHours()) : d.getHours();
    var m = (d.getMinutes().toString().length == 1) ? ('0' + d.getMinutes()) : d.getMinutes();
    var s = (d.getSeconds().toString().length == 1) ? ('0' + d.getSeconds()) : d.getSeconds();

    var time = h + '/' + m + '/' + s;

    return time;
}

var myTime = getDateTime(1435986900000);
console.log(myTime); // output 01/15/00

If you want to convert Unix time duration to real hours, minutes, and seconds, you could use the following code:

var hours = Math.floor(timestamp / 60 / 60);
var minutes = Math.floor((timestamp - hours * 60 * 60) / 60);
var seconds = Math.floor(timestamp - hours * 60 * 60 - minutes * 60 );
var duration = hours + ':' + minutes + ':' + seconds;

for timestamp=1592426697 gives wrong number of hours (=442340) - can you fix it? – Mn 17/6, 2020 at 20:48

Code below also provides 3-digit millisecs, ideal for console log prefixes:

const timeStrGet = date => {
    const milliSecsStr = date.getMilliseconds().toString().padStart(3, '0') ;
    return `${date.toLocaleTimeString('it-US')}.${milliSecsStr}`;
};

setInterval(() => console.log(timeStrGet(new Date())), 299);

You can play around with the format (source):

const date = new Date(yourTimestamp).toLocaleDateString('de-DE', {
    weekday: 'long',
    day: '2-digit',
    month: 'long',
    year: 'numeric'
})

Result:

Sonntag, 01. Januar 2023

The answer given by @Aron works, but it didn't work for me as I was trying to convert timestamp starting from 1980. So I made few changes as follows

function ConvertUnixTimeToDateForLeap(UNIX_Timestamp) {
    var dateObj = new Date(1980, 0, 1, 0, 0, 0, 0);
    dateObj.setSeconds(dateObj.getSeconds() + UNIX_Timestamp);
    return dateObj;  
}

document.body.innerHTML = 'TimeStamp : ' + ConvertUnixTimeToDateForLeap(1269700200);

So if you have a timestamp starting from another decade or so, just use this. It saved a lot of headache for me.

If Timestamp is a numeric integer string, it must be converted to integer number first:

<!DOCTYPE html>

<input type="text" id="Date_Timestamp" size="50" oninput='
document.getElementById("Date_Timestamp_Conversion").innerText = 
new Date(this.value) + " _ (Converted to Local Time) \n" +
new Date(this.value).toString() + " _ (Converted to Local Time) \n" +
new Date(this.value).toUTCString() + " _ (Converted to Universal Time, UTC, GMT, GMT+0, GMT-0) \n" +
Date.parse(this.value) + " _ (Timestamp _ The Date is first converted to Universal Time, then converted to Timestamp)\n" +
( isNaN(this.value) ? "Not a Number _ (Timestamp to Local Time)" : new Date(parseInt(this.value)) + " _ (Converted to Local Time)" ) + "\n" +
( isNaN(this.value) ? "Not a Number _ (Timestamp to Universal Time)" : new Date(parseInt(this.value)).toUTCString() + " _ (Converted to Universal Time)" ) + "\n" +
"";'>
<br>
<span id="Date_Timestamp_Conversion">(Type\Paste a "Date" or "Timestamp" in the input box above!)<br></span>
<br>
2021/03/19 = March 19 2021 _ ("Year/Month/Day" _ Supported)<br>
03/19/2021 = March 19 2021 _ ("Month/Day/Year" _ Supported)<br>
19/03/2021 = Invalid Date _ ("Day/Month/Year" _ Not Supported)<br>
<br>

<script>

d = new Date();
document.getElementById("Date_Timestamp").value =
d.getFullYear() + "/" + (d.getMonth() + 1) + "/" + d.getDate() + ", " + d.toLocaleTimeString([], {hour12:false, timeZoneName:"short"});

</script>

I was looking for a simple, short solution to this problem as well. That's why I created this function.

You can easily expand the functionality. This function has all the options I need. It's basically doing the same as the php date function.

function date_format(unix_timestamp,format){
    const date=new Date(unix_timestamp*1000);
    const dateObject={
        'Y' : date.getFullYear(),
        'm' : String(date.getMonth()).padStart(2,'0'),
        'd' : String(date.getDate()).padStart(2,'0'),
        'H' : String(date.getHours()).padStart(2,'0'),
        'i' : String(date.getMinutes()).padStart(2,'0'),
        's' : String(date.getSeconds()).padStart(2,'0'),
    };
    var dateString='';
    for (let char of format) {
        if(char in dateObject){
            dateString+=dateObject[char];
        }else{
            dateString+=char;
        }
    }
    return dateString;
}

console.log(date_format(1667127654,'H/i/s')); // 12/00/54
console.log(date_format(1667127654,'Y-m-d H:i:s')); // 2022-10-30 12:00:54
console.log(date_format(1667127654,'d.m.Y')); // 30.10.2022
console.log(date_format(1667127654,'H:i:s')); // 12:00:54

Example 1

 var d =new Date("2023-01-22 00:00:00").toLocaleDateString('en-IN');
// "22/01/2023"

 var d = new Date("2023-01-22 00:00:00").toLocaleString('en-IN')
//"22/01/2023, 00:00:00"


const date = new Date("2023-01-22 00:00:00");
console.log(date.getDate() + '/' +  date.getMonth()+1 + '/' + date.getFullYear());

Example 2:

const date = moment.unix("1666632563").format("DD/MM/YYYY");
console.log(date);

//10/12/2024

Example 3:

const date = new Date(1666632563517);
console.log(date.toLocaleString());

//"10/24/2022, 10:59:23 PM"

Example 4:

const date = new Date("2023-01-22 00:00:00");
console.log(date.getDate() + '/' +  date.getMonth()+1 + '/' + date.getFullYear());
//> "22/01/2023"
