Generally, once you set up your iPhone, the time zone is automatically set based on your region or current location. But, you can change it manually without the need to change your location.
If your iPhone isn’t reflecting the correct time and date for your region, even after setting up, or you just want to change your time zone, here’s how to go about it.
First, Tap the Settings Icon, then scroll down and select “General.”
Next, tap “Date & Time.”
Afterward, disable the “Set Automatically” by toggling the slider.
Once you disable it, select “Time Zone.” Then, type your current or preferred location on the new page into the search box.
If you can’t find your specific town or city, type in your country’s name and tap it.
After selecting, your iPhone’s date and time will reflect the current time and date in that location. And that’s that!
