[systemd-devel] Timer: time format

[Mikhail Kasimov]

Hello!


Due to system.time 
(https://www.freedesktop.org/software/systemd/man/systemd.time.html) we 
have a construction "year-month-day hour:minute:second".

Hence, OnCalendar=*:12:00 construction means ' run my service at any 
hour on 12th minute on 00 seconds'. To specify 'running every 12 hours 
', use, for example, OnCalendar=00,12:00:00 or OnCalendar=*-*-* 
00,12:00:00, which is equal. Or, if you need to run your service twice 
on specified day (for example): OnCalendar=Mon,Fri 00,12:00:00 (on 
Monday and Friday at 00 and 12 hours).

Something like this way...
