To wit, the -3rd hour of the 12th June 2012:
$ perl -MTime::mkgmtime=mkgmtime -E 'say scalar gmtime mkgmtime
0,0,-3,12,6-1,2012-1900'
Mon Jun 11 21:00:00 2012
$ perl -MTime::Local=timegm -E 'say scalar gmtime timegm
0,0,-3,12,6-1,2012-1900'
Hour '-3' out of range 0..23 at -e line 1
This behaviour is very much required. It allows one to perform all kinds
of simple date/time arithmetic; e.g:
sub midnight_four_days_ago {
my @t = gmtime;
$t[3] -= 4; $t[0]=$t[1]=$t[2] = 0;
return mkgmtime @t;
}
