As others have said already that is not necessary.  You need to 
distinguish two concepts:

1. point in time: this is represented by a number of milliseconds since 
a particular point in time in history.

2. representation of a point in time for various audiences (language, 
time zone).

Ideally internally to an application you use concept number 1 _all_ the 
time and make use of concept 2 when appropriate (e.g. when presenting a 
point in time to the user or writing it into a logfile).

You can - but it's the wrong approach.
