Q: iOS 8 Calendar on iPhone showing GMT times for new events.

Before I saw this discussion thread I went to the Genius Bar and the genius there told me she had never seen this problem before and found it very strange that my phone was automatically sent to Cupertino time she had "never heard of that" being a default time zone for an apple product!!

She called for her genius  supervisor and he said this was clearly a problem with the exchange server and had nothing to do with the Apple software.

I too am more disappointed that Apple wont own this problem as a software glitch and rather points fingers to the exchange serve, etc.

This is a BUG in iOS 8.  It started happening on my devices right after the iOS 8 update.  I have spent hours working with the Genius staff at my local store and my Exchange host.  We have totally isolated this down to a bug in iOS 8.

The "(GMT)" thing only shows up on appointments that were created on an iOS device and then synced to another iOS device.  If I create an appointment on Outlook, it syncs down to ALL my iOS devices without the GMT transposition.

So what does this tell us:

1.  The problem cannot be generated by the Server/Exchange Host.  If it was, then an appointment created through Outlook would show up with the (GMT) thing on all the iOS devices that sync to that server.  If the buggy data comes from the server, and all the iOS devices get their data from the server, then an appointment created on the server and synced down to the iOS devices would show up with the buggy data on all the devices.  Instead the buggy (gmt) thing shows up on none of the iOS devices if an appointment is created on the server by a non-iOS device.

2.  The (GMT) problem is generated only when an iOS device receives a Calendar appointment that was created by another iOS device.  Non-iOS devices (i.e. Outlook) do not show the incorrect time or any (gmt) tag etc. This means that the original iOS device puts some sort of data into the appointment that only another iOS device can read.  That's an iOS problem.

I am near certain this is generated by something having to do with the time zone override feature in iOS.  I think it uses GMT as the reference timezone for all events and then depending upon how you set "time zone override" it then knows how to adjust the events based on whatever time zone you are in when you look at them.  What's happening is that due to some bug in iOS8 it is making a conversion and displaying the (GMT) time even if you have the time zone override disabled.

It is astonishing to me that a bug of this magnitude made it through the extensive beta testing Apple did before releasing iOS 8.  Even more astonishing is that Apple so far appears unwilling to address the issue even though there are widespread reports of it.  Apple please take note:  this is a deal-killer issue for corporate customers who's organizations use Exchange.

This is the sort of shoddy quality control, and "blame everyone else" approach I would expect using Android which is a major reason why I ditched Android for iOS a few years ago.  If Apple is OK with sinking to the level of Android then it is no longer differentiated by quality control and support, and consumers should go back to simply comparing prices and hardware specs.  Maybe Blackberry has a chance to get back a bunch of Apple customers??  Probably not, but Apple should think about this sort of thing.

This is incredibly disappointing.

Interesting, but your results are not quite the same as mine.  In fact, they're the opposite.

If I create an appointment on an IOS device, it's fine, and propagates fine to my other IOS devices.  If I create an appointment in Outlook (whether or not I'm using Exchange), it propagates to the IOS devices with the extra GMT timezone.  I agree with you that it is related to the timezone override, though.

This seems to work for me. It hasn't updated the older events to fix the timing, but the new events I've added to the calendar seem to be behaving. Hopefully it's a solution that sticks!

I Had the same issue on post with a different time zone, check on general settings> calendar> time zone override it mist be off

Same issue. GMT shows up on Facebook events and Google calendar events. Really just annoying and would like to display the event in my timezone or hide it.

The calendar event itself (for me) is showing in the right time so for example my event is showing up in the 10 AM CST block on the calendar, but the description has reads 4 PM (GMT).

Switching "Time Zone Override" on or off does not fix the issue I and others are describing here.  Even if you entirely delete sync accounts on the iDevices, confirm Time Zone Override is off, and then re-create the accounts, the unwanted GMT transposition still occurs.  Even after a complete factory reset, confirming Time Zone Override is off and resyncing, the same problem persists.

My suspicion is that this problem is being generated by a fault in the Time Zone Override coding in iOS.  Unfortunately simply disabling it doesn't solve the problem.  Apple needs to fix iOS to deal with this.  This is a widespread problem.  My Exchange Host, AppRiver is working on multiple tickets with Apple engineering on this, and when I talked with them to report this issue, they said they have many other users experiencing the same problem.

My guess is that this affects anyone who syncs their iDevices with any service other than iCloud....so hundreds of thousands of users.  What blows me away is that this never came up during beta testing iOS.  I have to assume that....at least a dozen (sarcasm)..... of Apple's beta testers sync using services like Gmail or Exchange.  How is it possible that not a single person identified this and reported it to Apple prior to the public release?

Not just GMT. In my case PDT or PST times are added to any appointment in the iOS8 calendar (both on my iPhone 6 and my wife's iPhone 5S).

What time zone are you actually in?

Did not work. My iCloud settings were correct (East Coast), yet Cupertino was set for iOS 8 time zone. It's an annoying bug

Eastern time zone

I've been watching this discussion for a couple weeks now, as I'm sure hundreds of others are as well.

I have a corporate VIP user with the same issue.  Our exchange server is in EST, our office is physically in MST, and all of his calendar items show PST.  The issue began when he upgraded to iOS 8.

Time Zone Override does not resolve this.

Removing and re-adding the exchange account does not resolve this.

A factory reset of the iPhone does not resolve this.

We're confident this is an issue 100% on Apple's side of things, not our own settings or configuration.

The reason I chose Apple is because it was simple and worked, now it's just turning to crap, I've had nothing but problems since iOS 8 and this calendar thing is really screwing up my work as it's confusing all the people overseas I share it with!

I've tried everything started above and like others have said as soon as a named calendar syncs to my iPad or iPhone the GMT appears!

Yup.... my calendar is totally MESSED UP!!!!!

APPLE please fix this!!!

The only time that i finally decided to use iOS calendar is the time that it didn't work!!

The event is set at the correct time, time zone are all set, too

but is seems to appear as PDT...

I'm using SGT and all my events are delayed!!!
