You cannot manually set a custom time on your iPhone. iPhones automatically sync with your carrier's network time.
However, you can adjust the time zone to match your current location. Here's how:
- Open the Settings app.
- Tap on "General."
- Select "Date & Time."
- Turn off "Set Automatically."
- Choose your desired time zone from the list.
You can also use the Clock app to set alarms and timers.
Note: Changing your time zone will affect all apps and features on your iPhone.
