Getting the time zone support right

When I take an international trip I can never seem to get this right, and calendar events go slip-sliding all over the place.
I have tried by time zone support on and off, but still previous events seem to get displayed wrong no matter what I do.
Currently I'm in Tokyo. Next Friday I'm going to St. Louis for a couple of months. I have a customer call on June 6th at 10 am central time. I just added it to my calendar by entering "Call with Coaches on June 6 at 10 am CDT" (see screenshot) and it created this event which correctly shows it taking place on June 7th Japan time. And I added a note about the actual time just in case.
So how should I have it set so when I am in St. Louis it shows up as June 6 at 10 am?
And what will happen with all my other events where I typically don't specify a time zone?
Thanks,
Doug

Hey Doug Lerner2,
Thanks for the question and superb details. I can understand how confusing Time Zone support can sometimes be. In my experience, everything is going to relate back to the main Time Zone Support drop down menu at the top left of the Calendar. This is the easiest way to quickly switch the Time Zone you are viewing.
Once you travel to St. Louis, simply switch the time zone of your calendar (if it had not automatically switched) to see all of your events in the local time zone (including events that don’t specify a time zone). So if you had your event set for June 6th at 10am CST, once you switch the Time Zone to central time you’ll see that that event is displayed correctly. All of your events that were created in Japan will move to their respective times, and you can also have “Floating” events that will ignore the time zone, and always be at that set time.

HT4576 I want to set up appointment times for an overseas trip before I go, and see those local times in the places I visit, but also be able to set new appointments while I am traveling, in the local times. Can I do this with Time Zone Support? If not,

I want to set up appointment times for an overseas trip on my iPhone 4S before I go, and have them appear as I put them in (for the local time) when visiting other countries. I also want to be able to adjust times and set up new appointments when I am overseas for the local time. Can I do this using the Time Zone Support or any other way?
Basically I want to do what I can do with a piece of paper - write down the time for when I will be there, and have it viewable when I am there, but also be able to put down new times while there.

Hi.
Regarding your question about reverting back- yes, I think you can. If you make a backup of your current configuration in Server Admin (by dragging the configuration file to your desktop- cool, no?) then you can load that one back in should your configuration not work. If you have the manual from Apple it should describe this process.
Network speed post-op? I don't think you will need to worry. Even using home directories stored on our OS X Server there is no network slowdown (that you can notice or that impacts the wider LAN in any case). It shouldn't slow down access to files, applications (which still come from the local drive anyway) or individual internet connections (even with filtering).
In our experience some of these things have actually got faster- but a lot of that is user perception. Same goes for people who will know you have configured the server and that they are now accessing files through your network from the server, and who really think it is slower. File coming from your local hard drive will always be quicker- but network access isn't that bad that it will make you barf and run in the opposite direction.
Something to look at: connection speed between clients and switching technology in your office. In other words, what kinds of switches are you using, what line speed have you got (100MB/s?) and is the connection from your server to the switch gigabit? Make sure it is.

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?
TNX

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.

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 can't add events to Exchange only if I change the time zone

Hi, I recently update my MacBook from Snow Leopard to Lion (10.7.3) and I was using iCal with Exchange in my organization without any problem, but now I cannot add events, I get a message saying that iCal can't add the evento to Exchange, and it gives me 3 options Cancel, Restore or Redo.
I search in the forums for this message but none has come to a posible solutions, but I found a discution that someone enable the time zone support and specifies a diferent time zone in the event and "voila" it fixes the problem, the events now are added to Exchange; but obviously this turnaround is not good because the meetings you have to mention the difference in the time to get a meeting done.
Anyone knows how to report this situation to Apple Support?

Sorry I do not write to give solutions, only to mention I have the same problem. Additionally, I can share that for the same Exchange account server I can register new events from my iPhone and my iPad. In both instances, events are uploaded to the server and appear in my MacBook's iCal.

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.

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.

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?

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.

Why is the Time Zone incorrect in iCal?

I live in Hawaii and when I trun on the Time Zone Support (in Mail, Contacts,Calendars) and select Honolulu, it puts the time 1 hour earlier than the current time. (iCal shows 6:30 when the actual appointment is for 7:30). However, when I select Anchorage, Alaska, iCal is set to the correct time. If I turn off the Time Zone Support it sets the time 1 hour earlier - just like setting it to the Honolulu time. Can someone explain why this is happening. It start when I switched to Lion and iCloud.

Are you normally in Hawaii? What is your "home" area?

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!!

When I change the time zone of the clock, the "Date created" time information for my documents and image files in the Finder window (and in Get Info) is changed. Can I make the time info in "Date created" remain fixed regardless of the clock's timezone?

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.

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' *

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.

Where did the time zone selection go when making an event in Calendar?

So in iOS5 and iOS6 there was an option to select the time zone the event was going to be in when creating it in the Calendar app.
Now in iOS7 it appears it is no longer there unless you turn time zone support ON.
I want to be able to have time zone support OFF like I had in iOS5 and 6 and still have the time zone selection option when creating events.
I'm at a loss for why this option was removed. Is there any way to get this back? My coworkers are having issues creating meeting events when out on the road and figuring out the right time zone +/- when moving between time zones.

You can middle-click a tab with the mouse scroll wheel to close that tab.
Did you try Save mode to be sure that it is not caused by an extension or theme?
Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.
