How do I get my Samsung Galaxy Grand Prime to stop activating the automatic time zone?

[AC Question]

I keep manually turning off automatic date/time and automatic time zone in settings, but shortly therafter, end up with the wrong time. When I go back to settings, both are turned on again. Very frustrating for someone living right on the time zone border!

Welcome to Android Central! Do you have any power saving modes or Easy Mode turned on? (I doubt power saving would change this, but just thinking of things that might do things automatically.)
