iphone calendar off by 1 hour after daylight savings

i have my iphone synced to my outook 2007 through an exchange server. after daylight savings this weekend, all of my appointments are now off by 1 hour. they are all correct in my outlook and on the exchange server (verified by web browser). i've tried deleting the exchange account from the phone and reinstalling, but that doesn't work. also, when i try adding a new appointment on my iphone, it shows up off by one hour in the exchange calendar. my iphone is currently showing the correct time.

anyone know what the heck is going on?

I use iCal to track my appointments. After the fall-back, my appointments are still the same on the computer, but are one-hour later on the iPhone. The phone shows the correct time and date. I have tried restarting the phone, deleting the calendar from the sync, and even creating a new calendar to send to the phone. The iPhone still thinks all appointments are an hour later. Any solutions would be appreciated.

I have been experiencing this same problem. My iPhone syncs with the company Exchange server.
I thought my issue was being caused by my being in the Central Time Zone US when the 'fall-back' occurred, but it seems unlikely now that I see others are experiencing the exact same 1-hour-off-meetings schedule as well.

I don't physically sync my iPhone for calendar, events, email. It's all through Exchange. I do sync for iTunes music and photos (Google's Picasa).

Found this on another site - it worked for me

Go to Settings -> Mail, Contacts, Calendars -> scroll right down to the bottom, there is a option called Time Zone Support. Have you tried setting this to the correct time zone? For some reason this is not linked to your current date&time settings.

Hope it helps, let me know...worked for me

I also had success using this method, from above:

On iPhone, go to Settings>Mail, Contacts, Calendars.
Scroll way down to Time Zone Support. Note that it's listed as GMT-4. Turn slide button to OFF, then back to ON. Note that it automatically goes to Washington, DC (GMT-5).

Calendar appointment times now correct.

Time on the iPhone updated automatically for daylight savings, but the Time Zone Support function didn't make the one-hour shift; they ended up out by an hour from one another. Forcing Time Zone Support to refresh its settings was all that was needed.

Thanks for the suggested work around... it worked for me.

But the really baffling thing is, why the **** doesn't the iPhone just use the current time as provided by the mobile network. The phone already has a built in clock. It would be best to just use that clock.

As it is now, not only is the extra-configuration annoying, it is also buggy.

Even worse, if I visit another time-zone, it should list everything in respect to the local time. Newly created contacts should always be created in the local time. Granted, there is complication in scheduling across time zones.

I'm glad it has worked for everyone, but I'm still getting issues. I'm using the Nuevasync (using exchange server) to sync to the iCal on my phone. It looks like it's taking random events and shifting them back an hour. The thing is that I live in Arizona and we don't do daylight savings.

I don't know how to fix the problem because it only does it to about half of my events. And I know the problem isn't with Google because their calendar has all the right times.

I tried making all the changes mentioned above, but those events stay put. Don't know what to do.
