This is a bug report for perl from sune.karlsson@esi.oru.se,
generated with the help of perlbug 1.35 running under perl v5.8.6.

[Please enter your report here]
timelocal in version 1.10 of Time::Local is not -w safe:
c:\temp>perl -MTime::Local -we "print timelocal(localtime())"
Use of uninitialized value in integer addition (+) at C:/Program/Perl/lib/Time/Local.pm line 76.

As far as I can tell this comes from the second call to _zoneadjust (line 77) where
$MinInt (= -2147483648) is fed to localtime which doesn't work to well with negative arguments.
