Bug #32057 for DateTime-Astro-Sunrise: bug in DateTime::Astro::Sunrise : "You need to have a longitude"?

This bug occurs in module DateTime::Astro::Sunrise version 0.01_01 (Mon Mar 17 10:01:50 2003). I tried to use this module to get sunset/sunrise times for the point with 0 longtitude and 0 latitude: #!/usr/bin/perl use DateTime; use DateTime::Astro::Sunrise; my $standpoint = DateTime::Astro::Sunrise->new(0, 0, undef, 0); #end But perl died at line 6, saying: You need to have a longitude at b.pl line 6 even though I have said the longitude should be "0" (instead of 'undef'). $ uname -a Linux somehost 2.6.22.1 #1 SMP PREEMPT Thu Jul 12 18:41:25 HKT 2007 i686 GNU/Linux $ perl -v This is perl, v5.8.8 built for i486-linux-gnu-thread-multi Copyright 1987-2006, Larry Wall Perl may be copied only under the terms of either the Artistic License or the GNU General Public License, which may be found in the Perl 5 source kit.
