This morning I was 45 mins late for something important. A few days ago my phone displayed the wrong time, because it was unaware of the changes to the AU daylight savings this year. Knowning I had something important on this morning I corrected the time last night (as my phone is my alarm) and all was good. Until I got a call asking me where I was this morning! Even though I manually corrected the time, how did that happen....
Seems Windows Mobile automatically updates it's time when it sync's, mine syncs emails and stuff every 15 mins.
Actually these daylight savings changes has caused lot's of issues. We have numerous customers with servers out of sync all over the place.
