如何调整它以使用本地时间获取昨天的日期?
use strict;
sub spGetCurrentDateTime;
print spGetCurrentDateTime;
sub spGetCurrentDateTime {
my ($sec, $min, $hour, $mday, $mon, $year) = localtime();
my @abbr = qw( Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec );
my $currentDateTime = sprintf "%s %02d %4d", $abbr[$mon], $mday, $year+1900; #Returns => 'Aug 17 2010'
return $currentDateTime;
}
