Correct me if I'm wrong: this is already done in 
pve-commen:src/PVE/JSONSchema.pm: pve_verify_timezone.

The current pve_verify_timezone function still uses 
/usr/share/zoneinfo/zone.tab which seems to be a subset of timedatectl 
list-timezones (418 vs 598 entries). That could be subject of another 
improvement.
