This will show you how to change your realm from Development to something else.

Code:
<Realm1 Name = "Test Realm"
        Address = "127.0.0.1:8129"
        Icon = "PVP"
        Population = "1.0"
        TimeZone = "1">
All you do is change the TimeZone to one of these:



1 - Development
2 - United Stated
3 - Oceanic
4 - Latin America
5 - Tournament

These are tested and work on the newest ArcEmu...

I will test other numbers to see...
