Not the above poster but I find you just tend to wake up about 2am because your body thinks it's 10am and time to get up.

Yes, I don't have a choice. My body wakes me up at 2:00 because it is past my normal wake up time in my home time zone. I've tried going back to sleep, but wind up just lying in bed awake.

That happened to me on my last trip to Europe. Both my wife and I woke up every night at 2:10am for the first few days. The precision of it was crazy. However, we would take a few ambient and be right back asleep and feeling great the next day. Amazing what twelve hours of sleep can do!

It's only mildly awkward to go to bed at 6pm, and then when you fly back east, you don't have much jetlag in that direction either. 2am in China is 11am in SF.

(I'm assuming the OP is flying from the US, based on the destination choices.)

EDIT: removed bad NYC math.

Did you get SF and NYC mixed up? Isn't 8am SF == 11am NYC?

Yes, also the offsets are wrong. China (East coast time right now is 9 hr diff from West coast usa. After daylight ends it's another hr diff. It is never a 6 hr diff.

> China (East coast time right now is 9 hr diff from West coast usa.

BTW, all of China is on Beijing time.

True, though if you go significantly to the west, many people will keep track of a more sane local time too.

Yep; ironically, that's what I get for doing math while jetlagged.
