Changing host timezone from script (HCI)

Hello,
we've been having problems with our host's time. Every now and then the timezone changes and the clock of all the VMs goes back by one hour.
I would like to automize the process of setting the host clock correctly with a script so that we don't need to access the HCI and manually do it everytime.
Is there a way to interact with the timezone settings from code? Maybe some APIs?
Thanks

use tzutil command. do script to run it

Yes, there are APIs that you can use to interact with the timezone settings on a host and automate the process of setting the host clock correctly.

One commonly used API for this purpose is the "tzdata" library, which is used by many Linux distributions to manage time zone data. You can use this library to read and set the system time zone from a script or application.

Yes, it is possible to automate the process of setting the host clock using a script. In most operating systems, you can use command-line tools to interact with the timezone settings and automate the process of setting the correct time.

Here are some examples of how you can set the timezone in different operating systems:

On Linux:

You can use the timedatectl command to set the timezone. For example, to set the timezone to "America/New_York", you can use the following command:


timedatectl set-timezone America/New_York

On Windows:

You can use the tzutil command to set the timezone. For example, to set the timezone to "Eastern Standard Time", you can use the following command:


tzutil /s "Eastern Standard Time"

Once you have set the timezone on the host, you can use any scripting language (such as Python or Bash) to automate the process of setting the correct time. For example, you can use the ntpdate command on Linux to synchronize the host clock with an NTP server:

ntpdate -u pool.ntp.org

You can then run this command periodically (for example, using a cron job on Linux) to ensure that the host clock is always accurate.

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.

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

API is the best way to use this

Use the API to do this

you can check the tzdata for linux

Epoch is favored for IoT applications, however ISO is preferable for other day-to-day applications owing to human readability and so forth.

Yes, you may use a script to automate the process of configuring the host clock and timezone. The particular approach you choose will be determined by your operating system and programming language.
