I travel internationally extensively for work. I have always had my iPhone Time Zone set to "Set Automatically." When I arrive at my destination and connect to the WiFi, the iPhone correctly set the time.
However, since iOS 11, now when I turn my phone to Airplane Mode when I go to bed, the time zone reverts to my home time zone. This caused me to miss an alarm that I set!!! Please fix this!!
iPhone 6s, iOS 10.1.1
This worked for me. I think everything was working fine while we travelled until I changed Facebook's location services to "while using the app" because Facebook was chewing up battery charge. Make sure you follow the path all the way to the setting as adviced by TheLastPagan: Settings > Privacy > Location Services > System Services > Setting Time Zone and turn this on. It is deep in iOS. I have two iPhones and only one had the issue with the only difference the Facebook location services so that's why I am suggesting this may have something to do with it. Regardless, if Setting Time Zone is off for any reason it won't update your time zone automatically.

Update to IOS 11.3.1 and after 6 months of arguing with Apple and a user on here they finally fixed this critical error. Who in their right mind would be happy with paying $1500 for a product that you cannot turn off is beyond me. #f ools
This appears to have been fixed in iOS 11.0.1.
If you go to settings>privacy>location services>system services - is setting time zone on or off?
Updating my phone to the beta version of iOS 11.2.5 has fixed this problem on my phone and the associated problem on my Apple Watch (as outlined here).
Contact Apple to report it. I am having the same issue and also someone that lives close to me is also having the same issue. i was talking to Apple this morning as they wanted a log from me. The more people that report it direct, the quicker we will get this fixed.
I arrived in Las Vegas yesterday from London and my 8+ on 11.2.5 changed to local time despite not having the ‘set automatically’ enabled. It has kept doing this despite turning the facility off. HOWEVER, a possible solution has occurred to me. There is a setting in iCal that is ‘time zone override’ Having selected that and locked it to London, my phone has stayed on London time for over 12hrs now. Fingers crossed!
Hiya. Before you throw all your iOS kit out maybe try the following. In iCal settings, select ‘Time Zone Override’ and select your preferred place. I’ve set mine to London and despite travelling all over the world as a pilot my system time has stayed fixed to London for at least a month now. Good luck!
Actually no, the time zone is updating, but it strangely reverts back to my home time zone when in Airplane Mode. This bug was introduced when I updated to iOS 11. I'm hoping it gets fixed in 11.1. If not I'll try reinstalling iOS as you suggested.
I have a related problem - when I travel, I prefer to set my time zone manually, so I turn off "Set Automatically." But on a new iPhone8 with iOS11 (and 11.0.1, but not sure yet about 11.0.2), the time zone setting changes to turn on "Set Automatically" at some points I that seem to be related to using airplane mode.
I am having the same issue and have the same preference—keep the phone on my home time zone and not automatically update. The phone keeps reverting back to automatically set time zone. I am on version 11.1.2. Will this be fixed in another update? Anything else I can do?
Same problem here. I have an iPhone 8 on iOS 11.2.
Turned off the "Set Automatically button", however after each wifi connection i do, again the buttons turns itself on...which is 1 hour late fro my current place time. I hope this thing reaches Apple...and a fix coming soonest
Checking in... Still happening on iOS 11.2.1
I can reproduce the unwanted flip back to "automatically set time" on by rebooting the phone. I set auto time set to off and manually set a time... Then Pressing the power button , selecting "turn off" then turning phone immediately back on via the power button
If you are fast enough after it boots up you can unlock it and see it's ok on the correct manual time then it connects to network and flips back an hour. You go to date time settings and "automatically set time" it turned back on. This happens if I forget all my wifi networks. So it seems to be something it's getting from my carrier att.
I get the carrier is pushing a time and zone but why won't iOS ignore that if I manually set a time and tell it to not auto set?
I am having exactly the same problem on iPhone 8 Plus. I set the phone to Manual and within a few minutes it reverts back to auto. This is extremely annoying as I live on the time line boarder of NSW and QLD (NSW side) but as my phone number is a Qld number, my phone keeps showing Qld time ( 1 hour behind). My iPad 2017 is not a problem as I don’t have the SIM card installed but it has gps, so must me SIM card location related. I am also using the IOS beta updates but is obviously not fixed in the upcoming IOS updates. It should not be reverting back to Auto once set to manual regardless of where I live. I will be contacting Apple today to officially report this expensive bug.
