we really do NOT need 4 times zones in the US. Why not consolodate to 2 (China spans 5 but standardize on one zone http://en.wikipedia.org/wiki/Time_in_China) I am not one of those people that thinks every China does is groovy, but in this case they are on to something. I think that there is more comercial benefit to 2 time zones in the US that we get from daylight savings time, the time for which has come and gone. Why not just have East and West TZ's?
