[systemd-devel] OnCalendar every X minutes

[Max]

Hi.

Is there a way to make timer unit which will execute things every X minutes where X
is not divisor for 60?
In case of divisor it's obvious:

[Timer]
OnCalendar=*:00/10

Will run every 10 minutes which nicely fit into 60 minutes hour. What if I would like
to run things every 11 minutes: 0, 11, 22, 33, 44, 55, 66, 77...

If I interpret http://www.freedesktop.org/software/systemd/man/systemd.time.html
correctly than 
OnCalendar=*:00/11 will run on 0, 11...44,55,0,11... resulting in unevenness at the
end of an hour.

Am I missing something?
If not - are there plans to introduce such notion like OnCakendar=every 11 min. ?

cheers,
Max.
