If your iPhone is showing wrong Time and Date, the problem in most cases can be fixed by modifying Date & Time Settings on your iPhone.
iPhone Showing Wrong Time and Date
If your travelling and find your iPhone Showing Wrong Time, the problem is mostly due to your device not being setup to automatically correct its Time & Date based on your Location.
If you are not travelling and find your iPhone indicating incorrect Time, the problem could be due to your iPhone obtaining Date & Time from incorrect Carrier settings.

The solution in this case is to allow iPhone to automatically Set its Date & Time by contacting Apple Servers.
Go to Settings > General > tap on Date & Time.
On the next screen, enable Set Automatically option.
After Enabling Set Automatically option, make sure iPhone is showing the right Time next to Time Zone entry.
