Even that's not enough, because the stupid humans keep changing what
the time zones mean.  Say you find a file that has a stored time of
2007 MAR 31 17:00 UTC.  If that file was written before 2005, then the
offset to US Eastern is 5 hours.  If that file was written after 2005,
the offset is 4 hours.  Which did the human mean when they instructed
the computer to write the file?  No way of knowing, in the general
case.
