Computers can find out (or somebody can find out) where a specific computer

in a variety of amusing (and sometimes annoying or frightening) ways.  So it is
quite possible for a laptop to find out what time zone it is in, when it
updates the time.

Well, sure - *if* you're willing to accept the fact that if geolocation gets it
wrong, you just missed your meeting.  And it's not perfect.  Don't believe me,
wander over to the NANOG archives and search for all the postings where people
have gotten screwed over because they're in New Jersey but somebody's
geolocation thinks they are in France...
I saw similar when I was in Maine a couple of winters. For some
reason, the geolocation database thought I was in Canada (it did not
muck with time zone data, though).

Perhaps laptops need a GPS?
