1) it relaxes your brain because you are so helplessly lost as to what "real" time it is in your city, you transend time and just get into good states of flow.

2) it forces you to do mental time zone math in your head making you a better programmer

3) helps you realize your city does not dictate what time units you use, you control that. Maybe all us programmers should switch to UTC. End daylight savings time. And finally get like a swatch beat system going.
