The latter. Basically, for each element in the expression one item of the
specified list must hold for the event to trigger.

To express what you want to express I'd just list all days of the
first week.

Sun 1,3,5,7,9-1,2,3,4,5,6,7 02:00

Which means: on every sunday, that is one of the first 7 days of the
months 1, 3, 5, 7 or 9, at 2am.

Of course, we should probably introduce a ".." syntax so that
1,2,3,4,5,6,7 could be written as "1..7". Happy to take a patch for
that.

Hope this is useful.

Lennart

Very good. If I follow you correctly, the service will be triggered on
month 1,3,5,7,9, 11 (in fact, every two months. I do not care which
one indeed),  on the first Sunday of these months at 2:00 AM. That is
exactly what I want.
As a side note, I will need to trigger like 8 services at this moment
(in fact, it is a letsencrypt ssl web certificate auto renewal for all
my subdomains). It seems there is no After= for timer, so best would
be to set, say 2:00, 2:05, 2:10 etc (the ssl renewal just need less
than one minute). Or simpler, let 2:00 for all of them ?

YOu can use After= between the service units you trigger, if you like.

But if it's not a problem that all your services run in parallel, by
all means run them in parallel, and specify the same time of 2:00...

[systemd-devel] On calendar timer

2016-01-06 Thread arnaud gaboury 
I am not sure about how to express date/time in a timer unit.

I want the timer to be start every year(*), on month 1,3,5,7,9,11,
first day of month at 02:00:00 AM. Here is what I wrote:

[Timer]
OnCalendar=*-1,3,5,7,9,11-01 02:00:00

Is this correct ?

Now if I want instead not the first day of the cited months, but the
first Sunday:

OnCalendar=Sun, *-1,3,5,7,9,11-01 02:00:00

Or the above will only trigger the service IF first day of the cited
month is a Sunday?

Thank you for help
