Does the iPhone Automatically Change Time Zones in iOS 9?

Many people rely on their iPhone to tell them the current time and date. So if you are about to fly somewhere, or if daylight savings time is approaching, then you may want to make sure that your iPhone is set to update the time (and even date) automatically.

While the iPhone is capable of updating the time automatically, it is possible to change an option that gives you manual control over this information. Our guide below will show you the menu on your iPhone where you can check to make sure that the device is ready for a time zone change or a daylight savings time adjustment.


Here is how to set up your iPhone so that it automatically changes time zones –

  1. Open the Settings menu.
  2. Select the General option.
  3. Select the Date & Time option.
  4. Tap the button to the right of Set Automatically to turn it on. The setting is on when the button is green.

These steps are repeated below with pictures –

Step 1: Tap the Settings icon.

There is another setting that can also affect your iPhone’s ability to update the time. It is a setting on the Location Services menu, and is found by going to:

Settings > Privacy > Location Services > System Services

To ensure that your iPhone will automatically update the time zone based on your geographic location, then you want to make sure that the Setting Time Zone option is turned on. It is turned on in the picture above.

One minor caveat to the iPhone’s ability to update based on a time zone change is what happens regarding scheduled calendar events. There is a setting for the iPhone calendar called Time Zone Override. This can be found at Settings > Mail, Contacts, Calendars

If the setting is turned off, as it is in the image above, then your iPhone will adjust the times for calendar events based on your current time zone. If you would prefer to have calendar event notifications go off based on a different time zone, then you will need to turn on the Time Zone Override and select the time zone that you wish to go by.

If you would prefer to have manual control over the time and date on your iPhone, then see what changes you need to make to allow for it. newsletter
