Yes, it definitely worked before (I've been running this and other timers for about a month). I don't remember how I inferred that rule, but I think it was this bit from systemd.time(7): "Either time or date specification may be omitted, in which case the current day and 00:00:00 is implied, respectively. If the second component is not specified, ":00" is assumed." But I don't see any definition for these components, so maybe I'm wrong and my timer only works by accident. > Either way, it cretainly could be a bug. Perhaps, since it's back to the way it was before: # systemctl list-timers NEXT LEFT LAST PASSED UNIT ACTIVATES Mo 2015-03-30 02:00:00 CEST 1h 44min left Mo 2015-03-30 00:00:00 CEST 15min ago backup-hourly.timer backup@hourly.service [...] Greetings -- Marc Joliet -- "People who think they know everything really annoy those of us who know we don't" - Bjarne Stroustrup
