Re: [systemd-devel] Question about OnUnitInactiveSec= directive

Seems, AccuracySec=1us parameter resolves this problem indeed:

Haven't read about AccuracySec parameter in man-page carefully. :(

Resolved. Thank you again!

We see 22:05:02 (end of update-session) --> 23:05:13 (start of next
update-session) --> 23:05:17 (end of update-session) --> 00:05:20 (start
of next update-session) --> 00:05:24 (end of update-session) -->
01:05:50 (start of next update-session) --> 01:05:55 (end of
update-session).

Question: Why time of new update-session is *not* equal to time of end
of previous update-session + 1h in section of seconds, e.g. 23:05:17 +1h
= 00:05:17; 00:05:24 + 1h = 01:05:24 and so on? Is here a way to reach
this precise coincidence?


Please check with "systemctl status" or "systemctl show" when unit was
actually deactivated. Also see "AccuracySec" timer parameter.
