On Ubutu:
If you get 0.system for the version, this means you have the version that PHP shipped with. For a newer version, you must upgrade via the PECL extension (sudo pecl install timezonedb)
http://pecl.php.net/package/timezonedb
timezone_version_get
(PHP 5 >= 5.3.0, PHP 7, PHP 8)
timezone_version_get — Gets the version of the timezonedb
Parameters
This function has no parameters.
Return Values
Returns a string in the format
YYYY.increment, such as 2022.2.
If you have a timezone database version that is old (for example, it doesn't show the current year), then you can update the timezone information by either upgrading your PHP version, or installing the » timezonedb PECL package.
Some Linux distributions patch PHP's date/time support to use an
alternative source for timezone information. In which case this function
will return 0.system. You are encouraged to install the
» timezonedb PECL
package in that case as well.
Examples
Example #1 Getting the timezonedb version
<?php
echo timezone_version_get();
?>The above example will output something similar to:
2022.2

On Ubuntu:
If you get '0.system' for the version, this means PHP is using system version of timezone database. For a newer version, simply upgrade 'tzdata' package without installing any PECL extensions:
sudo apt update
sudo apt install tzdata
