The Sun bug id is #4067374.

But I fail to see what's the difference between US/Pacific and PST8PDT, as
they're both the same zonefile.

The version of perl I have installed, version 5.004_04 doesn't call
localtime(0), but rather localtime(2*$DAY).  Perl 5.003 does call
timelocal(0).


So it would appear that if you use a later version of perl, the check in
Pilotmanager can safely be removed.

I'm not quite sure why perl things that timelocal(0) says anything useful 
about the current offset from GMT and/or summertime.
