Date, time, and time zone settings play an important role with many applications (like browsers, web APIs). If a standard or local user alters these settings, it can be very problematic for the administrator of the machine. But, there is a way to allow or disallow a standard user from altering these settings on a machine.
To do this you will need an administrative account on the machine. Log in with the administrative account credentials and follow these instructions.
