Hello Mille,

I made a bunch of fixes for time handling in SMS back in 2014, but
those patches have never been merged master I think. If you want to
rebase them onto the current master, they may help you (or may not -
they have fixed a lot, but I don't remember about this issue
specifically).

The patches reside in the achemeris/sms_fixes branch of openbsc:
