Bushfiva (if it's 19:59 on Tuesday just as you approach the date line, it will be 21:01 on Monday shortly after you cross it) - but I, for one, don't reset my watch every time I overfly a time zone change.
Tough luck about the two days' work for one day's pay, but hopefully you'll make it up on your next west-bound trans-Pacific flight.
