Daylight Savings Time - Calendar Problems

I am having exactly the same problem; it started saturday and is still happening (Monday 11/5).

Some, but not everything moved ahead an hour on the iphone when I synced it with my desktop machine. In addition, anything I created on the iphone appears an hour before on the desktop machine's calendar when it syncs. This is using an intel iMAC and synching with iCAL. All software is fully up to date (10.4.10 and latest iphone updates).

Would love to see Apple address this - it is clearly an "issue" and right no he only thing I can do is stop synching my calendars until it is figured out.

when I enter new apppoinments into the phone. Lets say I enter one for 10am... it will show up at 11am on the calendar. it seems there are many people having this problem based on another chain of the forum... stay tuned I guess...

Same problem here too. Mine started in Entourage. The detail view of the envent was fine but the quick look at the calendar view displayed the time an hour ahead. Then my iPhone started doing the same thing. I fixed the entourage issue by just deleting the event and redoing it. It has to have something to do with the time change. It's very annoying. I got around it on the iphone by directly changing it on the iPhone. But then next time it syncs it messes up entourage. This has been happening since last week for me.

On your iPhone, Go to Settings > General > Date & Time and turn the time zone support off then check your calendar items. If they are normal once again, you can turn the Time zone support back on. That was simple! If they are not fixed. Toggle the time zone support on and off. It worked for me the first time but other say it takes a few tries.

Good luck!

I have the opposite problem -- today I look in my Outlook calendar on the desktop and all entries I entered on the iPhone commencing on Monday (I had no entries on Sunday) are moved up one hour on desktop as a result of the synch I did yesterday (Monday). So now I'm getting desktop reminders one hour early. One of you geniuses out there must be able to figure this one out. By the way, both my desktop PC and my iphone clocks show the same time.

The solution below of turning off time zone on iPone I assume won't work for me, right? That only applies if the iphone entries got screwed up -- mine are correct. Thanks for the help.

I did what you suggested and then synched again, but all it did was convert all my previously correct iphone entries to one hour earlier (in other words, it conformed my iphone to my incorrect entries on the desktop, which were one hour early as a result of yesterday's synch). This is just ridiculous -- now I have to manually re-enter all those entries for post-DST shift events.

I had similar problems with the calendar on the iphone until I set BOTH timezone sections properly. That is, there is a time zone entry for Date & Time, and one for Calendar, and both should be set, regardless of whether you have "Automatic" and/or "Time Zone Support" turned on or off.

So, under Settings>General>Date&Time, turn "Set Automatically" off and then pick your correct time zone. I also turned on "Set Automatically" after setting the proper time zone there.

Then, go to Time Zone Support and turn that off, then pick your correct time zone. I leave the support off because I always enter my calendar times for local time in the time zone I'll actually be in (e.g., a 10:00 meeting in London is set for 10:00 in my calendar even though I live near philadelphia, because it want it to be set for 10:00 when I'm there in London).

Ever since setting both time zone sections, I've not had any problems. It turned out that the date&time setting was set for cupertino, though I never noticed it because set automatically was turned on. So even though I'd set my calendar time zone properly, odd things happened because somehow the cupertino time zone was effective for certain things.

Anyway, just a few thoughts.

I already manually corrected the times of every prospective entry I could find on my Outlook calendar and then resynched.

I also did what you suggest and yes, there was Cupertino under the calendar setting. So I changed it to Atlanta. Are you saying that when I now turn "time zone support" off, the iphone will still remember my city selection, even though it no longer appears in the box?

Maybe the Cupertino default caused my problems. I'm assuming when I originaly set date and time I never set a time zone for calendar. But it seems odd to me -- I'm in Atlanta, so why aren't my calendar entries on my desktop 3 hours early instead of one hour early?

Bump, same problem here. All my future events have fallen back an hour. Turning on time zone support doesn't fix. Would prefer not to reset the iPhone...

That worked for me - thanks so much!

there is a simple fix just go to your phone setting and then general setting, then date and time and input your timezone again, this should fix the problem.

yes, the problem is with the sync after you fixed your time zone on your iphone you had to do the same thing on your mac. that is the only way it fixes
