Mark Dain I have a problem at work I'm stuck on and I can't find anything online about this bug. Has anyone ever had a systemd timer configured `OnCalendar=*-*-* 01:30:00` (so 1:30 AM) but it's firing _every 12 hours_?! It runs 1:30 PM too as well as 1:30 AM. Other Linux boxes with "identical, as far as I can tell" configuration behave properly (run once every 24 hours at 1:30 AM). Ubuntu/17.04, Linux/4.9.36, systemd/232. Any tips greatly appreciated, been stuck for days on this! #ComputersAreNotDeterministic
