Turning off Time Zone Support

Hi,
I have recently moved countries which are 8 hours apart.
I have had Time Zone Support turned on in iCal and my iOS devices. I also use Google Calendars.
If I try to switch time zones, all my appointments move by 8 hours. I don't need to know what the time is in other zones, I suppose what I want is the "floating" time zone.
I have tried to export and reimport my calendars but the time does not change correctly. Do I need to edit the .ics file in some way?
Thanks!

Hi,
If you need it I have a script to move all events in a calendar by a number of hours. See the script Offset iCal Events here.
Best wishes

Cannot completely turn off time zone support in the iPhone calendar

In iOS7 it was possible in settings to turn off time zone support in the calendar. (This is not the same as having the date and time of the phone automatically change to current time zone which is generally what one wants and is not affected by calendar time zone support.) The problem in iOS8 is that Time Zone Override is not the same as Time Zone on/off. Here is an an example.
1) you live in Chicago and central time is your "home" time zone.
2) you find out about a meeting in New York at 1:00pm next week. You want to add the meeting to your calendar. If you add it at 1:00pm, when you arrive in New York (and change time zones), it will change the meeting time to 2:00pm.
Time Zone Override does not turn off the time zone calendar support. It provides two different views (time in current time zone and time in home tine zone). But time zones are irrelevant when I am scheduling an event at a known time. (Time Zone Override ON seems to work only if you are out of your home time zone and schedule something in your home time zone. But this is almost never what I encounter since I am usually at home, and need to schedule an event outside my home time zone.)

It would seem that way. But with "time zone support" on, you'll simply view your events "as if" you were in a certain time zone.
Example: I create an event in California for 6pm. ( A "California event") If I turn "time zone support" on, and select my time zone as Los Angeles, nothing changes. But if I select Oklahoma city, the time WILL change to 8pm, because it assumes I need to view a "California event" in Central Time.
"Time Zone Support" was created for people that have phone conferences in different time zones. The feature allows one standard time to be used in the calendar, and anyone outside the time zone can use "time zone support" to read it in thier respective time zone.
I'm saying this feature is trying to complicatedly simplify the calendar. I can use the organ between my ears to assume the correct time zone. And having to dig into my preferences in order to view my events correctly is completely insane.
All I want is to create an event, set an alarm, and not have to EVER worry about it changing.
I assumed that turning "time zone support" off would accomplish this as it did in the past. But the calendar STILL REMEMBERS WHERE AN EVENT WAS CREATED. So if the time zone ever changes, it will try to view the event according to the time zone you are currently in.
iCloud does the same thing. When you set your time zone on iCloud, it will view an event according to THAT time zone. If you are in Central time and create an event, your iCloud calendar better be set to Central time or else there will be a descrepancy between your phone calendar and your iCloud calendar.
I just want to turn off "time zone support" COMPLETELY.

How to "In Effect" Turn Off Time Zone on iCal AND main computer

I am hopeful that this will help those of us who don't want to have any form of Time Zone on our computers or iCal. I read some of the other posts and see that it does not appear an option to completely turn off all Time Zones on the computer and iCal.
What I am thinking about doing, is trying to "Trick" my computer & ical into thinking it doesn't ever go anywhere and thus leaves all of my appointments where they are - no matter what time zone I am actually in.
I hope those of you more knowledgable can please help me see if this will work, or not?
I am hoping that by leaving Time Zone Support turned "Off" in iCal and leaving my computer at a 'manual' Mountain Time Zone (meaning I don't have it set to have it automatically set to the right time - I will set it manually), my appointments will stay put (not move around 8 hours when I go to Italy &/or back to the US)?
I can set the time "manually" to the correct time when I am in either US or Italy so my computer will reflect the current time, but still be set in Mountain Time Zone? Will the alarms still work on calendar events?
The only drawback I can see so far, is that all of the times on emails are messed up (i.e., off by 8 hours) when I am actually in Italy because I still do have the main computer time zone set as Mountain Time - US.
I am willing to live with this (I think?) if it leaves my appointment times alone.
Someone on a similar thread had wanted iCal to function like a paper planner - that is exactly what I am looking for as well! (it looked like that thread was a bit older, so that's why I posted this new question. It is my first on this type of forum, so forgive me if I am doing something wrong - and please advise! :~)
PowerBook G4 Mac OS X (10.3.9)

I am being driven crazy by, what I suppose to be, the same issue. I have used the Time Zone Support feature to somewhat limited success.
I frequently travel between different time zones am confused on how to set up iCal to show the times of my events *in the place where they occur*. When I am in LA and I have a concert in Chicago later in the week, I don't need to know what time the Chicago concert is in LA.
Syncing my Treo 650 adds another problem. Publishing the calendars adds another as the published times are not listed in the time zone where the events occur but rather what time zone my laptop is in.
This seems simple to me, but I may be missing something. Here are my wishes:
1. As I travel with my MacBook Pro that I can change my Date and Time preference to actually list the time zone where I am. Easily done...but...
2. That the event times in iCal are unaffected by the changing of the Date and Time preference adjustment...(after all the concert in Chicago is still at 3pm on Friday, even if I am in Tokyo on Monday. I need to know the time of the Chicago concert in Chicago time, not Tokyo.)
3. That calendars that I publish list the time in the place where the event occurs. I have students that need to know their lesson times but are consantly confused because the published times reflect whatever time zone I happen to be in...not where the lessons take place.
4. That when I sync my Treo the event times automatically adjust to whichever time zome the treo picks up off the network time server. When I land in a new time zone, I need to know the the rehearsal starts at 10, in the city where I have just arrived.
I have recently switched to the Apple PIM apps from Entourage...where, if I never changed the time zone, everything was fine.
Sorry for the longish cry for help.
Thanks

Time zone menu does not appear when I turn on time zone support

I am trying to change the time zone on my calendar. When I turn on the time zone support in advanced preferences no time zone menu appears. Does anyone know another way to change the time zone?

The Time Zone menu appears in the System/Date & Time/Time Zone preference pane.

Time Zone support

I understand the basic gist of time zone support as it is pretty straight forward, but I'm constantly finding myself confused when I use time zone support when I travel. For instance, I use EDT and sometimes put events in my calendar that I know I'll have while I'm traveling. If I put an event in my calendar for 2:00 pm because that is when the event is supposed to start, but the event is taking place in California, the event shows up in my calendar at 11:00 am and I get all confused as to when my events are actually supposed to start.
Is the best policy to figure out what the adjusted time is supposed to be and make the adjustment beforehand, or is it best to turn off time zone support? It gets really confusing when trying to add events to your calendar when the events take place in different time zones.
Any thoughts on this subject would be greatly appreciated
Mac

Simple answer is that the events should not be moving if the setting has stuck, so it's probably a preference file that has been corrupted.
Do you see the time zone at the top right of the iCal window?
If it's there even though you have unchecked the option in preferences, it might be worth going into preferences and rechecking, quitting preferences, going back in and unchecking.
If that fails to get rid of the zone in the window (or it wasn't there in the first place), you probably need to trash the preferences file for iCal:
Quit iCal.
Look for this file ~/Library/Preferences/com.apple.iCal.plist [That's in the Preferences folder of the Library folder of your home folder in case you don't understand the notation.] Drag it to the desktop - or somewhere convenient (so that you know where it is and can put it back if iCal gets screwed-up).
Restart iCal.
This should start iCal in the default mode - which is with Time Zone support off. You will notice that the position and size of windows, default view (month, week, day), etc have also been reset - so you will need to arrange them to your liking and check that the preferences that you need are set correctly.
You should now be able to change time zone without everything moving. If it works, you can trash the file you moved to the desktop.
If this doesn't fix your problem, you can at least get back to where you started by:
Quitting iCal.
Dragging the original .plist back over the new one.
Restarting iCal.
* Make sure you back-up your data before doing anything. However, I just tried this with my own iCal and it all worked 'as advertised' *

HT4576 "Time Zone Support" in Calendars should be renamed to "Override Time Zone Support"

So, I live on the East coast and notice, while on a trip just outside Cupertino, that my iPhone Calendar wasn't updating to the the local time, even though my iPhone had correctly updated to PST.
Finally, at the end of my trip, oh so nigh to Cupertino, I find out that my Calendar's erroneous display of time was due to the "Time Zone Support" configuration option.
This is a GROSS misnomer.
iOS requires the specification of a timezone - else the time would be set arbitrarily and would waste the time (NTP) service provided by the cellular provider.
Thus, the "Time Zone Support" option under "Mail, Contacts, Calendars" should be relabeled to "Override Time Zone Support" AND the ability to assign an event to a time zone should always be available (though defaulting to the current time zone - unless a 'Default Time Zone' configuration option is added).

The behavior you are seeing is actually inherent in most calendar apps -- the deal is that you are telling your calendar when something happens, not what time. Our company writes a calendaring+task management app for iPhone called Pocket Informant - we get this same question on occassion, so I wrote up a Knowledge Base article discussing some details (keep in mind - this article discusses some features specific to our app that you won't find in iCal/Calendar on MacOS X):
http://webis.kayako.com/Knowledgebase/Article/View/123/0/why-do-the-times-change -on-my-appointments-when-i-travel-to-a-different-time-zone
In iCal/Calendar on MacOS X, when you turn on Time Zone support, you then get to choose the time zone that you are entering your appointment for. This helps you not have to do the "time zone math" in your head. Thus, if you are in CST and want to set up an appointment for 6pm PST, you can choose PST in the event editor as you enter 6pm. Note that while you are in CST, your event will display in your calendar at "CST time" (8pm), but when you fly out to PST, it will show the "correct" PST time.
While iCal/Calendar supports "floating time zones", I personally would caution against using them for everything (I mentioned a few reasons why in the above kbase article). Use those for events that truly are "time driven" rather than "point in time" driven (such as "I want to go jogging every morning at 5am no matter what time zone I'm in).
Hope that helps some!

ICal time zone support problem

my problem is not that it goes out of sync, but according to the iCal help, there is supposed to be a "pop-up menu in the upper right corner of the iCal window." I have no idea what that means, because i don't see a thing.
I am still on tiger, btw.
thanx!

caitanya,
In order for you to display that selection open iCal>Preferences...>Advanced and choose [✓] Turn on time zone support.

What does time zone support do on iCloud? Should I leave it off or turn it on?

I find time zone support to be one of the most confusing things Apple does.
If I travel from Chicago to Florida (Central to Eastern time) my appointment times change on the Mac.
I'm not sure what they will do on the iPhone,
and really, what does it do in iCloud? It is an advanced option as I found out when all my Chicago appointments showed up two hours earlier in the cloud.
I changed to Central time, using the instructions on iCloud, but what is the value of time zone support there? The Apple server is not moving when I travel. Should I just leave it turned off?

they are not always on the same time due to daytime saving time changes twice a year in Israel which are not syncronized with any changes in Gaza, Beirut, etc.

Exchange/Outlook and iPhone 1 hour off, and Time Zone Support is OFF

Hi, in reading thru the threads about Accepting an appointment in an iPhone shifting the appointment 1 hour ahead in the iPhone and Outlook 2003, the consensus is that the issue is with a bug in the Time Zone Support setting in Mail, Contacts and Calendars, and that either refreshing this setting or disabling Time Zone Support fixes the sync. At our facility there were 2 iPhone 3GSs that had this issue and the refresh fixed only one of them. The other persists in moving the appointment forward 1 hour after accepting on the iPhone; if the user accepts from Outlook, the correct time is reflected on the iPhone. The strange thing is that the appointment time is correct when it shows up in the calendar inbox, you can watch it move the appointment forward after pressing accept on the iPhone!
I've double-checked everything on the Outlook/Exchange side, the time zone and DST settings are correct. This user has noticed this behavior after DST in March.
Anything I'm missing?

Why is iCal Time Zone Support hidden?

Last week my wife sent me an iCal appointment for 2pm but I received it as 11am. On checking her iPhone she found the same time, 11am. We had both been overseas recently. On our return we had reset our time zones on our iPhone's and laptops to Auto so no problem there. Obviously we were very puzzled.
I then checked the Apple support page and found a lot of people had the same problem with Mountain Lion although I'm running Mavericks.
What I did discover was that in iCal > Preferences> Advanced is hidden a button called Time Zone Support.
Why put it there? And why is it off by default?
We turned it on on my Mac Book and hers then switched it off then on again on our iPhones and low and behold the appointment times changed to 2pm on all our devices.
I don't understand why changing time and date settings or having them on Auto shouldn't adjust all native apps and hiding the setting in advanced preferences just seems ridiculous.
Maybe that's just me?

I'm not sure how putting something in the user Preferences for an app hides it, but...
And why is it off by default?
I got into an argument with someone about using time zones in Calendar. He only wanted the times to show up as local times regardless of which time zone was selected and what time zone had created the event. I think he actuall missed some appointments when travelling overseas. His assistant had set up the appointments, and when he looked at them before he left, they were listed as late in the day because he was looking at his current time zone.
So, I guess that is why it is off by default.

With Time Zone Support on Calendar no longer automatically adjust to the local timezone.

Apples support forums are riddled with Discussions about problems with being able to dicate a specific time zone for appointments. Many of these postings, as well as their corresponding solutions, are unnecessarily lenghtly when the root cause of all of this is a one very simple mistake by Apple. Right now to be able to assign a specifc timezone for an appointment using the Calendar app on the iPhone you have to have "Time Zone Support" turned on in Settings. The problem is that when you turn on this feature the Calendar app stops automatically updating the calendar to reflect the local time zone you are in. These are simply two seperate items that have no reason to be tied together. Apple could easily correct almost all of the issues people are having with this topic if it simply split this into two seperate options that users can turn on/off seprately:
1.) Enter time zone for each appointment. YES/NO
2.) Adjust Calendar to the local timezone. YES/NO
It is virturally incomprehensible that Apple has not fixed this. It was clearly a mistake.

I have this problem too and am frustrated - it's not solving no matter what i do. And now Siri is totally bonkers too on this new software update - can't even pull from my contacts when I ask her to look someone up. What the heck is going on at Apple software? Have they been hiring a bunch of arrogant, crap programmers? I am seriously thinking of not buying an iPhone again after having one for 5 years. So disappointed!!

ICal time zone support

Forgive me if this is repetitive. I do not regularly read these discussion groups. I've just noticed a little problem with iCal. We recently moved to another state and another time zone, specifically, from the Central to the Eastern time zone. Time Zone Support has always been clicked "on" in our iCal. Our iMac clock and time zone are set properly, to the Eastern time zone. I just noticed today that the iCal time zone on all my "events" is selected as "Central U.S." But they show up at all the correct times (i.e., Eastern U.S.) on iCal. Is this what Time Zone Support is supposed to do? Convert all the events to the time zone in which you are located? To add to my confusion, I just got an iPhone 3G, it's set to Eastern Time, and all the events synced from my at-home iCal show up one hour earlier than they should on the iPhone iCal. Any suggestions? Thank you!

suz..
I just did the following and it seemed to correct the issue:
- made sure my .me and iCal apps were set to the same timezone
- turned off timezone support, closed iCal, turned timezone support back on
- made sure i was not using 'floating timezone'
that seemed to clear things up.

Disable time zone support

Hello!
I have switched on support for time zones in iCal ages ago, or it switched on itself. However, i would like todisable it.
The problem is that i moved house and i am now in a different time zone, so all my old events are displayed an hour wrong.
I triedto play around with changing my time zone back where i used to be, then disable it, then changing back, etc. But it will always show up an hour wrong for whatever events i created in the old time zone.
Please help me to sort this out!
Thanks,
Bernhard

Do you use iCloud? If so, go to http://www.icloud.com and log in.
Then open the Calendars app from there, and click the cogwheel in the upper right. Go to Preferences > Advanced and turn off "Enable Time Zone Support".
Hopefully that will end your tie to the time zone support for your reminders.

Explain Time Zone Support?

Time zone support boggles me and I think Apple's approach is counter-intuitive for that. It shouldn't be so hard.
I make my appointments in MST zone while I work in CST. Calendar (computer) is set to CST also. I travel to MST and find my appointments all shifted up one hour both on my computer and my iPhone. Time zone support is turned off. So just now I changed my computer's time zone in Calendar back to CST and that fixed my problem on the computer. Will that also fix the phone? Will I be seeing CST instead of MST?
I want my appointments to be for the time I entered them into Calendar. I shouldn't have to do anything to make that be the case (in my mind).
Thanks.

If you are traveling btween time zones, then turn Time Zone Support On. When you create an event, specify the time zone. Since the calendar knows what zone the event is in, it will get the time right whatever zone the computer is set to.

When time zone support is on even when I am on Jerusalem, when i create an appointment the time zone for the appointment is immediately changed to Gaza and even when I change it manually it returns to Gaza.

I have a 4s iPhone on IOS 6.0.1 with an Israeli Cellular provider.
I use Gmail services an exchange to sync my colander contacts and mail.
When the time zone support is set to ON in the Settings->mail, Contacts, Calendars->Time Zone Support
The time zone is showing Jerusalem (I am located in Tel-Aviv)
When I create a new Appointment, It Immediately changes the time zone of the appointment to Gaza.
Even if I change it back to Jerusalem it changes back to Gaza every time.
Only when the time zone support is set to OFF in the Settings->mail, Contacts, Calendars->Time Zone Support
The time zone in Gmail is ok and does not appear on the iPhone. (This is ok)
Dose any one know how do I make the iPhone not change the time zone to Gaza? And still keep the time zone support on?
