The "tzdata" library, which is used by many Linux distributions to manage timezone data, is one extensively used API for this purpose. This library may be used to read and set the system timezone from a script or program.

Dates are represented numerically by epoch time. Ex 1623606902 This is the total number of seconds spent from January 1, 1970. It depends on where you should use ISO and where you should use epoch; for IoT applications, epoch is preferred, however ISO is preferred for other day-to-day applications due to human readability and so on.

Yes, you can automate the process of setting the host clock and timezone settings using a script. The specific method for doing so will depend on the operating system and programming language you are using.

Use the API to do this

API is the best way to use this

Check with your CMOS battery cell, its mostly happen if the cell get week or expired. You need to change it.

the timedatectl command, which is available on most modern Linux distributions.

Here's an example script that uses timedatectl to set the timezone to "America/New_York" (replace with your desired timezone) and synchronize the system clock with an NTP server:

#!/bin/bash
# Set the timezone
timedatectl set-timezone America/New_York

# Enable NTP synchronization
timedatectl set-ntp true
You can save this script as a file (e.g., set_timezone.sh) and make it executable with the command chmod +x set_timezone.sh. Then you can run the script with the command ./set_timezone.sh to set the timezone and NTP synchronization.

You can also use other programming languages to interact with the system clock and timezone settings, such as Python's datetime module or the date command in a shell script. The specific method you use will depend on your programming language and operating system.
