Comment 2 for bug 1858210

This is because Europe/Bratislava is a timezone alias (to Europe/Prague), and systemd currently parses the 'zone1970.tab' to the the list of valid timezones; however that file only lists actual timezones, not timezone aliases.

I opened upstream pull request to change systemd to parse 'tzdata.zi' instead, which lists both actual timezones as well as aliases, which should fix this and list all zones and aliases from 'timedatectl list-timezones'
