My iCloud iCal shows up a wrong time

Agreed with opinion, that incorrect timezone calculation is Apple's bug in iCloud.

BUT, try the following:

ajust Timezone in iCloud to a different city in the SAME timezone.

E.g.: Sverdlovsk (Russia) worked incorrect, but Male - Maldives (the same timezone) works fine.

Hope it'll be helpful.

Hi. Emilianos reply helped me as well. Dont know why but it did ;-). Thanks!!

One more step. Log out then log back in again.

I had tried switching from Boston to NYC (same time zone) with no improvement. However, after daylight savings hit, the event on my iphone corrected itself automatically to match the Mac and iCloud versions. Since then I have not had any issues.

I'm still not sure what happened or if the bug is fixed. It's scary because I'm afraid I'll miss future meetings if they appear an hour off on my iPhone.

I have not tried setting the timezone to "floating." What does that mean exactly?

I am from Buenos Aires , Argentina. This bug with the Time Zone is driving me crazy. I am one houre late in all my appointments when adding the entry into Outlook or icloud.com (I added it with start time 10AM and the appointment on iphone start 12AM). The "Flotante" thing from icloud.com is a good workarround, but do you have any fix for this issue when creating the appointment in Outlook 2010 ? (it is not possible to use another -3 TZ because all of them have daulight saving while Argentina doesn't have)

Apple -> Please fix this bug !!!!!!!!

I have experienced the same. It only seems to happen when a calendar event is created in another timezone ie i am on CST and the calendar event was created in EST. It shows correctly in iCloud but it shows as EST on my iPhone. So what I did was to change the timezone on the iCloud event to CST, save it and then back to EST. It hen corrected the entry on my iPhone. So clearly it does not send the correct timezone info to the iPhone on the initial sync. This is clearly a bug in iCloud to iPhone/iPad sync.

I agree Apple fix...

I figured out that when I am in the icloud settings (by clicking my name in the icloud home screen), I can choose time zone but I can ALSO scroll over the city and choose the city. I chose Denver CO rather than Phoenix (doesn't heed daylight savings) and went to the calendar...

Fixed.

I am having the same problem - i have made sure both time zones on my iphone and icloud are the same and i have turned them both off - no matter what device I use to make the calander entry, the icloud calander is always an hour behind - very irritating - fix it Apple - PLEASE!!!! And this has been happening since before daylight savings so I dont think they are related - I am in the Dublin time zone

And one more annoying thing - the BirthDay Calendar shows notifications the day BEFORE exact date inspite of setting to notify at 9:00 of the same day...

Think some step-by-step manual is needed made by Apple...

Emiliano's reply apparently is not a workaround, but in fact is the correct solution. What is infuriating is that if you search for "floating" in iCloud Help, you get no results of any kind. Evidently iCloud users are supposed to be good guessers when this problem arises.

Go to your iCloud settings. Make sure the time zone designation (from settings on the main iCloud page) doesn't mention "standard" time or some other setting that will disable taking daylight savings time adjustments into account. You make changes to the time zone setting by moving the vertical strip left or right on the world map. Hope this helps.

Be sure you pick your city for your time zone. I picked mountain time zone using Phoenix, AZ. The problem there is that Phoenix does not use daylight savings time and such. Once I set my time zone for my home city, also on Mountain Time, everything corrected itself. I did have to log out of icloud completely and then log back in for all the appointment times to be corrected.

thank you!!!! - it was set to canada central time zone but just moving it to chicago central time zone fixed it!

The suggestions listed here only work for calendar events that I make after setting time zones correctly on iCloud and indavidual events. None have made previously created events show up correctly...

I'm righting this post as a defeacto how-to for solivng the issue of Time Zone support for anyone who is having this problem with syncing time sensitive data between all of their devices:

I was having this issue with time zone support until I read through this chained discussion. The way to solve this is to manually fix your Time Zone settings for each iOS, iCloud.com, OS X you attach your iCloud account to. Read below to learn how to do so for all three.

From iCloud.com, beginning at the home screen:

Home>> Click on User ID at the top right next to sign out>> Time Zone>> select your Time Zone and city.

After a few seconds, your events and reminders should automatically adjust.

For iOS (I'm using my iPhone here):

Settings>> Date and time>> You have one of two options here. Either Set Automatically or select the time zone you are in. Initially mine was set to automatically. Somehow, turning it off for a moment before turning it back on seemed to do the trick here, revealing that it was the probable root of my problem.

From Mountain Lion:

System Preferences>> Date and Time>> Click unlock and enter your password to make changes, if necessary>> select TIme Zone>> again, you can either let Mountain Lion select the time zone automatically, or you can select it manually based on the closest major city in your zone. Simply turning off the Automatic option momentairly before turning it on again will probably do the trick here as well.

The point of turning these preferences off and on is allow all your devices to "reset" there time settings so that they can communicate on the same page. Following these steps should help in preventing a [tedious] trip to the Apple store.

Hope this helps!
