Summary: Specifying the timezone "IST" causes Date::Format's time2str() to return an "uninitialized value in addition" error, and returns UTC time labeled as IST. Distribution name and version (For example, "DBIx-SearchBuilder-0.46") TimeDate-1.20 from: http://search.cpan.org/CPAN/authors/id/G/GB/GBARR/TimeDate-1.20.tar.gz Perl version (Find this by running the command perl -v) $ perl -v This is perl, v5.6.0 built for 9000/777-hpux Operating System vendor and version (Find this by running the command uname -a) $ uname -a HP-UX psweb1 B.11.11 U 9000/800 305419896 unlimited-user license Details about your operating environment that might be related to the issue being described I had been using Perl scripts on a system hosted in the United States for a long time, but when the code was copied to a server in India I noticed this issue. I downloaded the latest version available from CPAN and it still has the issue. The "ist" time zone is commented out in Time/Zone.pm. I installed the module into a custom location and uncommented that line, and it appears to work. Exact cut and pasted error or warning messages: The example code below gives this error message, and a time is returned but it is UTC time, even though the returned timezone is "IST": Use of uninitialized value in addition (+) at /opt/perl/lib/site_perl/5.6.1/Date/Format.pm line 118. The shortest, clearest code you can manage to write which reproduces the bug described: #!/usr/local/bin/perl -w use lib "/opt/perl/lib/site_perl/5.6.1"; use Date::Format; use Time::Zone; use Date::Parse; my $timezone = "IST"; my $todays_date = time(); my $formatted_date = time2str( "%Y-%m-%d %X %Z", $todays_date, "$timezone" ); print qq{"$todays_date" formatted, and converted to $timezone is: "$formatted_date"\n}; exit; Output from the above script is: $ test_tz.pl 2>&1 Use of uninitialized value in addition (+) at /opt/perl/lib/site_perl/5.6.1/Date/Format.pm line 118. "1340058036" formatted, and converted to IST is: "2012-06-18 22:20:36 IST" A patch against the latest released version of this distribution which fixes this bug: $ diff latest/Zone.pm custom/Zone.pm 223c223 < # "ist" => +5*3600+1800,# Indian Standard --- Show quoted text
> "ist" => +5*3600+1800,# Indian Standard
