Synching past DST borders incorrect
Posted: Wed Nov 18, 2009 8:06 pm
Can somebody help me?
I have Thunderbird 2.0.0.23 with Lightning 0.9 on the pc and Windows Mobile 6.0 on my PPC (and birdiesync ofcourse).
I encoutered a problem with the same event being different om my pc and ppc. I dived into it and found where it was all about. Here an easy way to reproduce the bug...
When you create an event on the pc, at 20:00 on sun 25 okt 2009, it will be correctly synchronized to the ppc (displayed as 20:00 on sun 25 okt). However, if you only change the day of this event (on the pc) to sat 24 oct, it will display on the ppc as 19:00! And you know what, this is the night the daylight savings time correction jumps in...
The timezone on pc and ppc are correctly set (GMT+1).
Maybe you think, hey, why is an event in the past important? Well, to me it seems it cannot be trusted, and that's a dealbreaker for me. And btw., its even worse. Try now to make an event at 2 april 2010 on 20:00, it will sync to an 19:00 event on the ppc!!
It seems events cannot be made in an other than you current dst status.
Or am I missing something here? Please advice!
