timezone_version_get

Gets the version of the timezonedb

&reftitle.description; `string` `timezone_version_get`

Returns the current version of the timezonedb.

&reftitle.parameters; &no.function.parameters;
&reftitle.returnvalues;

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.
