# Does NOT use CPAN libraries, etc sub getModifyTime($) { my($file) = @_; my(@a) = stat($file); if (scalar(@a) <= 0) { return undef; } return $a[9]; } # Example use: use POSIX qw(strftime); sub main() { my $mt = getModifyTime('/etc/passwd'); my $str = strftime("%a %b %e %H:%M:%S %Y", localtime($mt)); print "mt=$mt str=$str\n"; } main();
