I know who can't do a simply time zone change, I have relatives on the East coast and in Hawaii (its own time zone), and I'm on PDT right now, so I always have to remember 3 hours ahead and 2-3 hours behind for hawaii because they don't do daylight savings like Nevada. Just remember your negative or positive number, I'm PDT/PST usually -8, meaning if the time were in GMT (greenwich [spelling?] mean time) I would subtract 8 hours from that time, GMT being base 0 for those of you who don't know.
