in the zonesramble

For a while now... maybe since Dylan moved to San Diego... I haven't had any trouble keeping Timezones straight for the USA. But yesterday one of the guys at work gathered people for a teleconference 4 hours too early because he did the math wrong for the Mountain time zone. (subtracted 2 when he should have added)

My trick involves a certain physicality: in effect, it's as if I'm overlaying the United States on the top half of a clock:
Then, it's easy to grasp how a mental timezone journey's west sets the clock back one hour. Each hop to the west has a matching hop backwards on the clock. (Hopefully my super-crude diagram makes things more clear, not less.)

Prior to this, I also mixed up how many hours back to go for, say, California time... I have little problem recalling that the country has 4 timezones, but before this "3 hops back system" it was easy to make what computerists call a fencepost error and subtract 4 instead of 3.

PS Am I crazy in remembering that Windows used to have a much niftier "timezone" interface that would highlight the area of the timezone as you selected it, and maybe even let you select a timezone by clicking on your area? My install of XP has a select list and then a static map of the world beneath, with no obvious interaction between the two. It almost feels as if some retarded patent stopped Microsoft from having the niftier UI.
