Nothing, except that POSIX defines the "time"(*) as being relative to
GMT.  When you read a zip file or tar file, you need a common basis
for understanding the time, else everything will be off by some number
of hours.  You can't determine this common basis without knowing your
time zone.


(*) The unit for time (time_t) is "seconds since the Epoch", Epoch
being Jan 1 1970 00:00 AM GMT.
