Fractional timezones, like -0330 (NST used in Canada) or +0430 (Afghanistan, Iran DST), were not handled properly in parse_date; this means values such as 'minute_local' and 'iso-tz' were not generated correctly. This was caused by two mistakes: * sign of timezone was applied only to hour part of offset, and not as it should be also to minutes part (this affected only negative fractional timezones). * 'int $h + $m/60' is 'int($h + $m/60)' and not 'int($h) + $m/60', so fractional part was discarded altogether ($h is hours, $m is minutes, which is always less than 60). Note that positive fractional timezones +0430, +0530 and +1030 can be found as authortime in git.git repository itself. For example http://repo.or.cz/w/git.git/commit/88d50e7 had authortime of "Fri, 8 Jan 2010 18:48:07 +0000 (23:48 +0530)", which is not marked with 'atnight', when "git show 88d50e7" gives correct author date of "Sat Jan 9 00:18:07 2010 +0530".
