iCal to iPhone times screwy

Have you checked the computer time zone selection for your Mac to be sure it is correct?

System Preferences > Date & Time > under the Time Zone tab.

Do you regularly travel outside of the Chicago or central time zone?

If not, there is no need to have Time Zone Support enabled with the iPhone.

Try turning Time Zone Support off on your iPhone, and make sure it is off with iCal.

Next, do a Reset, which is done by pressing and holding the Home button and Sleep/Wake or On/Off button simultaneously until you see the Apple logo and then release - ignoring the slide to turn off prompt when doing so.

Next with your iPhone connected, under the Info tab for your iPhone sync preferences below Advanced at the very bottom, select Calendars below "Replace information on this iPhone:"

Select Apply, and then sync.

Also, by the way, when I deselect Sync iCal Calendars, then sync, the calendars remain there. (This is why I re-downloaded the firmware, then Restored the iPhone, figuring that might help).

That's normal. It would allow you to have separate calendars on the iPhone and in iCal.

If it's exactly an hour difference the most likely scenario is that you don't have the timzeones set correctly. Is the clock correct in the iPhone? Do you have "Set Automatically" enabled in settings/date & time? Similarly for your computer? Every case we have seen of this issue thus far ultimately came down to settings on the computer or the phone not matching.

I was having a similar issue. Though my iPhone was showing the correct time for my time zone, synced events from iCal all had the wrong time.

Both the MacBook and iPhone time and date were set to the correct time zone.

However, on the iPhone when I went into Settings -> Mail, Contacts, Calendars, the "Time Zone Suppport" setting was still set to Cupertino. Once I corrected that and checked the calendar, all times were correct.

Apparently, the "Date and Time" setting under the "General" section of settings is not tied to the setting under "Mail, Contacts, Calendars."

Good Luck,

Also check your Time Zone settings in your Moble.me Calendar Preferences online! Mine were offset by 5 hours. Mobile.me should have read the settings from my synced computers. Somehow it got set for London Time Zone.

Hey thanks!
Problem fixed!!

I have a similar problem and mine is NOT fixed. I set appointments on my iPhone in iCal and then when I sync to my computer they get shifted back by 3 hours. This is totally annoying and frustrating. And I have checked, both my iPhone and my computer are set to the same time zone (Boston). I have tried resetting the iPhone and it fixed the problem but only temporarily.

Any definitive suggestions on how to fix this?
