I was using server timestamp in the smacks of Smacklet
So it was just PDT.

Per user request, I've made this truely global :)

User wanted an option of setting timezone. I thought it would be even better if I read the client side time using Javascript's Date() function. This way, even if the user moves to a different time zone, he/she will not have to change the settings! Yay! Me is very pleazed ;)
