Subject: [ruby-core:57748] [ruby-trunk - Bug #7445] strptime('%s %z')	doesn't work


Issue #7445 has been updated by felipec (Felipe Contreras).


=begin
So let's recap the current situation.

Time.strptime() has been fixed in Ruby Core, and Rubinious as fixed strptime() in both Time, and DateTime in rubysl.

So we have this:

=== Ruby MRI

 puts Time.strptime('1 +0100', '%s %z').strftime('%s %z')
 => 1 +0100

=== Rubinious

 puts Time.strptime('1 +0100', '%s %z').strftime('%s %z')
 => 1 +0100

 puts DateTime.strptime('1 +0100', '%s %z').strftime('%s %z')
 => 1 +0100

=== C

 #define _XOPEN_SOURCE
 #include <stdio.h>
 #include <time.h>
 
 int main(int argc, char *argv[]) {
 struct tm tm;
 char buf[0x100];
 strptime("1 +0100", "%s %z", &tm);
 strftime(buf, sizeof(buf), "%s %z", &tm);
 printf("%s\n", buf);
 return 0;
 }
 
 => 1 +0100

=== Perl

 use DateTime::Format::Strptime;
 
 my $format = DateTime::Format::Strptime->new(
 pattern => '%s %z',
 );
 
 my $dt = $format->parse_datetime('1 +0100');
 print $dt->strftime('%s %z'), "\n";
 
 => 1 +0100

And you still maintain that this is desirable?

 puts DateTime.strptime('1 +0100', '%s %z').strftime('%s %z')
 => 1 +0000

Come on, just apply the patch.
