Time travel, or time zones...
My sense of time is completely screwed up at this point... I just looked
at my watch, reading 23:00, and thought it was 2 o'clock in the morning.
Ugh, brain is completely confused. (hint: I never change my watch from
Pacific when I travel, preferring to just do the time translation mentally.
And I've spent a lot of time on the east coast in the past few weeks...)
