I hope they factor in global costs. Also when the DST stuff changed here in the states a while back, I either missed an update on my corporate managed machines (or something) cause I was showing up late in the Spring and early in the Autumn to various meetings during the dates in between the new and old dates. I eventually got a new laptop and didn't have the problem anymore :D However, I do remember many of our servers being out of sync at least for the first change, and we eventually just relied upon GMT dates and did a lot of fudging by hand with anything during those time periods.
