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' https://github.com/systemd/systemd/pull/20066 ** Also affects: systemd (Ubuntu Hirsute) Importance: Undecided Status: New ** Also affects: systemd (Ubuntu Focal) Importance: Undecided Status: New ** Also affects: systemd (Ubuntu Impish) Importance: Low Status: Confirmed ** Also affects: systemd (Ubuntu Groovy) Importance: Undecided Status: New ** Changed in: systemd (Ubuntu Impish) Assignee: (unassigned) => Dan Streetman (ddstreet) ** Changed in: systemd (Ubuntu Hirsute) Assignee: (unassigned) => Dan Streetman (ddstreet) ** Changed in: systemd (Ubuntu Groovy) Assignee: (unassigned) => Dan Streetman (ddstreet) ** Changed in: systemd (Ubuntu Focal) Assignee: (unassigned) => Dan Streetman (ddstreet) ** Changed in: systemd (Ubuntu Hirsute) Importance: Undecided => Low ** Changed in: systemd (Ubuntu Groovy) Importance: Undecided => Low ** Changed in: systemd (Ubuntu Focal) Importance: Undecided => Low ** Changed in: systemd (Ubuntu Impish) Status: Confirmed => In Progress ** Changed in: systemd (Ubuntu Hirsute) Status: New => In Progress ** Changed in: systemd (Ubuntu Groovy) Status: New => In Progress ** Changed in: systemd (Ubuntu Focal) Status: New => In Progress ** Changed in: systemd (Ubuntu Impish) Importance: Low => Wishlist ** Changed in: systemd (Ubuntu Hirsute) Importance: Low => Wishlist ** Changed in: systemd (Ubuntu Groovy) Importance: Low => Wishlist ** Changed in: systemd (Ubuntu Focal) Importance: Low => Wishlist -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1858210 Title: timedatectl doesn't list all timezones Status in systemd package in Ubuntu: In Progress Status in systemd source package in Focal: In Progress Status in systemd source package in Groovy: In Progress Status in systemd source package in Hirsute: In Progress Status in systemd source package in Impish: In Progress Bug description: Is there some filter determining which timezones are displayed by `timedatectl list-timezones`?
