[pve-devel] [PATCH manager/common 0/1] Fix #7175: switch API to timedatectl

[Stefan Mayr]

Using /etc/timezone is deprecated by the Debian tzdata package. The
Proxmox installer does not use it anymore. This switches the API to use
timedatectl as recommended by the tzdata maintainers.

At least pmg-api and pve-container use this. I would recommend to only
add a comment here instead of removing the helper since this is a shared
library. Alternatively, one could port all existing users to, e.g.
timedatectl.
