How can I change the time on my phone12 pro

Hi Cheriberry320,

Here are instructions for setting the date and time on the iPhone:

Change the date and time on iPhone - Apple Support

Please be advised that if you set the time incorrectly on your iPhone, you may encounter unexpected behavior with various functions of the device.

Cheers!

If time is set to automatic you can’t change it. And if Screen Time is enabled you cannot disable automatic time setting, as that would defeat the purpose of screen time restrictions.
