I noticed that if I set my device time manually, and turn off the automatic time sync on my iOS device, [NSDate date] returns the date and time assuming the device time is correct--which it may not...

I've got Ubuntu 16.04 LTS running in a Docker container (hosted on macOS). The date/time is off by about four days. $ cat /etc/*-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=16.04 DISTRIB_CODENAME=xe...

The issue is that System.currentTimeMillis() returns the wrong milliseconds with different ranges of time mainly within the future sometimes up to 6 months, but it varies from a few seconds to mont...

All I need is a way to query an NTP Server using C# to get the Date Time of the NTP Server returned as either a string or as a DateTime. How is this possible in its simplest form?

I have a motherboard with I/O pins and I have written a C library with functions to set and query the status of these I/O pins. Lets say the name of one of these functions is get_pin(int pin_no), a...

I have a distributed program written in java. I want my nodes access a synchronized physical clock. I know NTP is a protocol for physical clock synchronization. I know that I can install it on li...

Is there a windows API that would achieve the equivalent of clicking the "Update now" button in the "Date and time properties"/"Internet time" tab (opened by double clicking the clock in the taskba...

I'm trying to figure out what I need to send (client) in the NTP request package to retrieve a NTP package from the server. I'm working with the LWIP on Cortex M3, Stellaris LM3S6965 I understand ...

I am trying to figure out the best way to convert from epoch seconds (since NTP epoch 1900-01-01 00:00) to a datetime string (MM/DD/YY,hh:mm:ss) without any libraries/modules/external functions, as...

Let say I have code that uses the clock to generate ids. Or I have code that calculates time elapsed since an event happened. Or any other logic that expects system time to only move forwards, neve...

ntp doesn't want to jump your clock, because discontinuous time jumps are Bad. It wants to adjust your clock gradually -- very gradually. It's very conservative: by default, it won't slew your cloc...

I am writing an application that requires accurate timing. After asking this question, I have decided to investigate using NTP or maybe Simple NTP. Is there any open source implementation of these...

I've recently known about a gps.conf file in the /system/etc/ directory. Seems that tweaking NTP_SERVER values to NTP servers nearer to the usual location improves TTFF. Reading the source code in...

I'm looking for a way to synchronize time between clients with a good precision (let's say 0.5 seconds at least). I exclude using jsontime or exploiting timestamp in server response headers due to...

I was reading NTPv4 rfc to better understand the mechanism used by ntp. So, far the basic idea seems to be simple. But I am a bit confused regarding how NTP Clock Discipline works. In NTPv4 it says...

I am currently working on a license manager using java, I will be specifying a start and end date for my application so I can force a licensed user to re-license the program after a certain a...

I need create an application that validates NTP time synchronization on each machine. In other words, I need to determine if each machine is my LAN is synched to a common time server (stratum). So,...

i am working with Java and i am making a game. In this game the real time is very essensial part. For this reason i am trying to get the real time using Ntp. What i found in the web is this code. ...

I am working on an NTP Client. A few other threads indicate that the a message containing "\x1b' + 47 * '\0" is sent to the NTP server, but none of these threads give an explanation about what this...

It's about the Network Time Protocol, specified in RFC 5905. I understand that the Root Delay field of NTPv4 packets (or the Synchronizing Distance field, as it is named in the previous version NTP...

After I installed ntpd via yum I run the command systemctl enable ntpd.service and rebooted the computer. After I got the shell prompt I run systemctl -a | grep ntp and I got ntpd.service loa...

I'm looking for a programmatic solution that has the same effect as setting the "Configure Windows NTP Client" state in GPOE Administrative Templates > System > Windows Time Service > Time...

I am trying to measure the time elapsed between a message being sent from one machine and it being received by another. Initially I am measuring this in a network of EC2 instances. The EC2 instance...

Good day, I am attempting to implement a very basic NTP client just so I can query a remote NTP server (ie: pool.ntp.org) for the internet time to automatically set the time on my Windows developm...

I'm making a C++ software that needs to syncronize system clock with remote NTP server. For now, I'm ussing "system" command to call the console "ntpdate" command. ..But I think is an ugly w...
