i am being given advice to turn OFF Settings > Date and Time > Time Zone Tab > "Set Time Zone Automatically using Current Location" - presumably so that when i travel all my events stay at the time that i set them to. for instance in the case of a return airline flight, so that the alerts will alert me at the correct time.

 

right now - i think - that if the Time Zone updates and i am traveling east (say from CST to EST) then the phone changes all my appointments in Calendar and they all show up an hour LATER than when i originally set them. this way i miss my flight.

 

however, i am not sure if there are consequences to this.

 

also, i can't tell if i should also change the Settings > Date and Time > Date and Time Tab > and UNCHECK "Set Date and Time Automatically".

 

also, i am getting uber confused between the settings on my phone as compared to those on my MBP or on Calendar. Location Services i think is a iPhone specific setting whereas Calendar > Preferences > Advanced > "Turn on TIme Zone Support"

 

anyone licked this so that it all works?

    Hey hotwheels 22!

     

    I have an article for you that should help you choose the best preference for these settings:

    Thanks for coming to the Apple Support Communities!

    hi braden.

     

    i have tried this "empirically" a couple of times by traveling to another time zone but i was basically testing to see if i can get this to work. the first time i did this i did not get the alert that i set because something had gotten adjusted and the time of my event that i had set had gotten "pushed back" - i think basically due to the time change between CST and EST. this is a problem since when i travel it is helpful to have the alerts on my phone. right now i am having a hard time figuring out why it would not be the case - given the explanation in your tech articles - that this won't happen again if these settings are on. conversely, if i turn oen or both of them OFF - it is not clear to me what the consequences are.

     

    there is such as thing as a "floating" event which is supposed to (i think) alert at any time zone at the time that you SET the event - so that it does not ADJUST based upon your traveling to a new time zone. however, there appears to be a lot of confusion as to whether this works and/or to what extent it has limitations.

     

    for instance, is this a viable way to get calendar to work across time zones? i mean, the articles you helpfully post don't seem to address how this works from a practical perspective.

     

    here are my settings.

     

    MBP:

    Settings > Date and Time > Date and Time Tab > Set Date and Time Automatically (currently set to ON)

    Settings > Date and Time > Time Zone > Set Time Zone Automatically Using Current Location (currently set to ON)

    Calendar > Preferences > Advanced > Turn on Time Zone Support (currently CHECKED)

     

    iPhone

    Settings > General > Date and Time > Set Automatically (currently set to ON with “Time Zone” showing as Chicago)

    Settings > Mail, Contacts > Calendars > Time Zone Support (currently set to Houston)

    Settings > Mail, Contacts > Calendars > Time Zone Support > Time Zone Support Slider (currently set to ON)

     

    1. do i need to do anything special when setting an EVENT while i am in CST (for instance) but the event is going to happen while i am in EST? i mean, can i just set the event with these settings and leave it as CST?

     

    2. do i need to MANUALLY adjust my iPhone and MBP - once i arrive in EST - to show up as CST in order to get the alert to go off at the correct time?

     

    3. do i need to MANUALLY pull down an event to "FLOATING" any time this event will happen outside the time zone i am in?

     

    4. are there any limitations to using a FLOATING event? i know one cannot set a floating event from the iPhone but if this works and this is the only limitation i can do this method.

     

    5. i have heard some people resolve this issue by MANUALLY setting their time zone for their "home time zone" and they TURN OFF time zone support on all their devices so that the events happen at the correct time with no time zone adjustment. does anyone know if this method works? does anyone know if there are complications to such a move - for instance if i was to work in another continent for a period of time it seems like you would have to change your time zone and this would affect all previously entered events. but also i cannot figure out if doing this will let the TIME on my MBP and my iPhone read correctly since this is very important to me.

     

    sorry to be posting on this but this is very difficult to test and threads such as there indicate there is a lot of ongoing confusion about this.

     

    https://discussions.apple.com/message/24163748#24163748

     

    any thoughts? or perhaps there is someone that has travelled recently and has this down to a science?

     

    THANK YOU VERY MUCH

    Hi Braden,

     

    thank you for the help. the link is also helpful so thank you again for this. i am having a bit of a hard time in that i am not sure how to interpret this answer exactly.

     

    i mean, if i am understanding the current implementation then if i want to make a suggestion to the product suggestion forum - it would be to suggest that apple implement the ability to add FLOATING appointments on the iPhone and to have the ability for this to be the DEFAULT on both the computer devices and on the iPhone?

     

    this way (presumably) when travelling you can have all the settings i described in the OP as ON and checked - so that your phone reads the correct time when you cross time zones and there is no need to adjust a time zone for any of your devices manually?

     

    i mean - if this is correct it would be nice to know since it will help me manage my appointments until something is changed/fixed but it will also help me clarify the issue when talking to someone on the phone at Apple Support.

     

    anyway, a BIG thank you and if anyone has anything to correct me on here it would be great to know before i call someone at phone support on this.

     

    THANKS
