Comment 3 for bug 1733881

Oh, no, this probably isn't a systemd bug at all, this is probably due to you not having an /etc/localtime AT ALL. Which timedatectl won't be happy about, and will list as "n/a". Because you've literally not set a timezone.

(Note that /etc/timezone is just human-friendly input into tools that set timezones, /etc/localtime is the actual timezone, which usually either points to tzdata content, or contains a zonefile itself... If neither of these is true, then your timezone really is "unset", or "n/a", but defaults to UTC, so timedatectl is being accurate here)
