One Time Every where

Now, I wish If there was only one Time Zone For the whole entire World.
Imagine All the people wakes up at same time and goes to bed at same time.
No EST, No GMT, No IST...Just simple plain vanilla Time.
One Time Every where.

Specially, It's really painful to write a software code to handle all different Time Zones. A simple testing takes entire 24 hrs and by that time next date starts.
