Lovely. It's a leap year bug in upstream gpsd (fixed in newest release). Fortunately dates will start matching reality again on the 29th of February.

EDIT:

I've tried a minor patch and it seems fine -- except that Nokia has not released source for current osso-gpsd, so I can't be sure..

Current binary on OS2008 is 1.0-25, but I've compiled 1.0-23 with the patch for myself, if anyone else wants it go ahead: http://folks.o-hand.com/jku/osso-gpsd/. Will be interesting to see if this affects the time-to-first-fix...
