New issue by kintarowonders on void-packages repository

https://github.com/void-linux/void-packages/issues/38058

Description:
I created a new Void Linux system and the installer did not have UTC as an option and all of it's timezone options in the installer are region based. I decided to change this detail later.

So I searched for how to change the timezone on Void Linux and was [led to the documentation](https://docs.voidlinux.org/config/date-time.html).

I did this and changed the symlink in /etc/localtime to /usr/share/zoneinfo/UTC and then I rebooted, partly to be sure it was persistent. When I booted back up I was still in the timezone I picked in the installer. I decided to investigate and found out that the documentation is wrong, and that the timezone symlink is set on boot.

To actually change the timezone one must change the TIMEZONE variable in /etc/rc.conf and the documented should be updated to reflect this.
