Perl has daylight savings error
Last modified: 2007-04-18 12:31:23 EDT
From Bugzilla Helper: User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.2.17 i586) When perl reports dates it appears to have trouble with daylight savings, it adds 4hrs to the adjusted hour instead of the standard hour. Reproducible: Always Steps to Reproduce: 1. perl -e 'use POSIX; print(POSIX::strftime ("%a %b %e %H:%M:%S %Y",gmtime(1e9)),"\n")' 2. perl -e 'use POSIX; print(POSIX::strftime ("%a %b %e %H:%M:%S %Y %z",localtime(1e9)),"\n")' 3. date 4. date +"%s" --date='Sun Sep 9 01:46:40 GMT 2001' Actual Results: Sun Sep 9 02:46:40 2001 Sat Sep 8 21:46:40 2001 -0400 Sat Feb 10 00:21:44 EST 2001 1000000000 Expected Results: Sun Sep 9 01:46:40 2001 Sat Sep 8 21:46:40 2001 -0400 Sat Feb 10 00:21:44 EST 2001 1000000000 Note that in step 2 it reports that we are 4hrs away from UTC but that the actual time difference is 5 hours. On slackware 7.0,7.1, and current-20010208 the correct answers are given. This was tested on 3 different installations of rh6.2, and 3 different slackware boxes. The rh6.2 machines are independently administrated.
I suppose I should mention this is with perl-5.00503-10, perl-5.00503-12, and a second perl-5.00503-12. A manually compiled perl-5.6.0 supposedly did not have the bug. All 3 slackware's werte using a recent slackware perl package with 5.6.0 so this may be a perl 5.00503 bug.
