Time doesn't change at Timezone

Hey Go_Colts,

Thanks for the update. Just to make sure, there are a few other steps that you did not mention if you have tried them already.

"If you still need help

If your device still shows an incorrect date, time, or time zone,2 change each setting instead of using Set Automatically. For example, you might have iOS 9 or earlier and your country or region or government changes the time zone or the observance of daylight saving time. If so, follow these steps:

1. Go to Settings > General > Date & Time. 
2. Turn off Set Automatically.
3. Now you can change the time zone or the date and time:3

• • Tap Time Zone and enter a city with the time zone that you need. (Not sure which city to enter? Use the time zone map on timeanddate.com to find a city with a time zone that matches your needs.) 
• Or tap the date to change the date and time.  "

Greetings Go_Colts,

Thank you for using Apple Support Communities. It seems like there is trouble with the iPhone not updating the time zone. I would recommend you use this article to help troubleshoot the issue.

"See if you still need help after each step:

1. Make sure that you have the latest version of iOS.
2. Turn on Set Automatically1 in Settings > General > Date & Time. This automatically sets your date and time based on your time zone. If there’s an available time zone update, your device lets you know.
3. Allow your device to use its current location to determine the correct time zone. To do this, go to Settings > Privacy > Location Services > System Services and select Setting Time Zone.
4. Check that your device shows the correct time zone in Settings > General > Date & Time > Time Zone."
