I'm pretty sure that the time, is the time that their network operators computers are on.

Yeah tell me about iPhone weird alarm problem it seems manufacturers are having bad understanding of how daylight saving work

p.s. I also have this issue , my reoccurring calendar events are messed up , it went back for one hour , only fix is to create events again

i have asked other peoples on a forum and one of them has the same problem, i`m still trying to find the problem....

For what it's worth.

In Canada we went back 1 hour to standard time yesterday morning and my N900 corrected itself with no issues. I wasn't connected to data or wifi, so it must of come through the cellular network.
Not bad, considering that the N900 is not even sold in Canada.

I'm in Toronto and time went back for one hour, yeah it corrected itself but I have issue with events that had specific time occurring each week , do you have that kind of event?

My regular work-day alarms are working and I don't have a calendar event due for a week, so I'll see about that I guess.

My phone was updated corectly too, not connected to wifi or other things, just enable the autoupdate time and data, no issues with other things just the problem with the text messages i receive :-?? in the next days i will do some test and ask other friends witch have the same network operator as me and i will see if they have the same problem, i hope that i will resolv the problem its kinda annoying.....

ok...now this is weird, now i dont have any problem ) i receive a message like...right now and the time for my message was corectly ....i dont know what just happend...i think now its ok and i hope this will never happend 10q all who tried to help me.
