How to set Laravel Carbon timezone for timestamps?

Question

I have a project which is primarily based in CET region. I set CET in config/app.php, but all pivot timestamps in the base are stored in UTC time?

How can I set "global" timezone for timestamps?

i made this test:

<?php
$timezone = date_default_timezone_get();
echo "The current server timezone is: " . $timezone;
echo "<br />".date('m/d/Y h:i:s a', time());

$mytime = Carbon\Carbon::now();
echo "<br />".$mytime->toDateTimeString();
?>

and here's the result:

The current server timezone is: CET
06/09/2016 12:06:04 pm
2016-06-09 11:06:04

tnx Y

Not an answer to the OP, but if you are looking for how to change the timezone of e.g. zulu time input, it can be done like this Carbon\Carbon::parse('2021-01-28T23:45:00.000000Z')->setTimezone('Europe/Brussels')->format('Y-m-d H:i') => "2021-01-29 00:45" – Brassy

Answer 1

Update file config/app.php

Eg: 'timezone' => 'Asia/Jerusalem' instead of 'timezone' => 'UTC'

Accordingly

i think this is the answer for latest Laravel, right?? config('app.timezone') will affect the Carbon timezone, right? can anybody confirm it? – Pecoraro

I wouldn't recommend this IF you have deployed your application live already. Changing the timestamp globally means it will begin saving the timestamps in the database with the updated timestamp, meaning some rows of your databases will be saved with the old timestamp and others - with the new... – Embrasure

Answer 2

You can achieve it with accessor

public function getCreatedAtAttribute($value)
{
    return Carbon::createFromTimestamp(strtotime($value))
        ->timezone(Config::get('app.timezone'))
        ->toDateTimeString(); //remove this one if u want to return Carbon object
}

Downandout

That is an accessor not a mutator, but nonetheless I agree the best practice here (especially if your application spans timezones or is consumed in a timezone affected by DST changes) is to always save dates in UTC and just change the timezone when the date is displayed, not when it is stored. – Aerator

Thanks, this was the solution to my issue, as time zone was dependent on the user logged into the application. – Yugoslav

Answer 3

in the AppServiceProvider.php you can add the php functionality to alter the timestamp for the whole project

public function boot()
{
    Schema::defaultStringLength(191);
    date_default_timezone_set('Asia/Aden');
}

Behold

On Laravel, a best practice is modifiying the timezoneoption from the config/app.php file. – Teenager

Answer 4

Carbon uses the default DateTime PHP object, so use the date_default_timezone_set() function, for example: date_default_timezone_set('Europe/London');

It is an php.ini file setting named date.timezone = Australia/Melbourne. Thanks for pointing the function. – Circuit

Answer 5

If you are using Laravel Carbon TimeStamps, then you have to change timezone in App/Providers/AppServiceProvider.php file

// App/Providers/AppServiceProvider.php

public function boot()
{
    date_default_timezone_set('Asia/Calcutta');
}

Answer 6

It looks like solution is to use not "CET" but one of explicit timezones, for example: "Europe\Minsk"

First Step change on config/app.php

'timezone' => 'UTC',

change to

'timezone' => 'Europe/Berlin',

create a function using Carbon

Carbon::createFromFormat('Y-m-d\TH:i:sP', $product->created_at)
                    ->timezone(config('app.timezone'))
                    ->toDateTimeString()
