Time::HiRes

• Since 5.7.2, Perl has come with the Time::HiRes module

  • Time::HiRes overloads time and sleep to have finer resolution

        use LWP::Simple 'get';
        use Time::HiRes 'time';
        my $url= shift;
        my $start = time();
        my $doc = get($url);
        my $elapsed = time() - $start;
        print "$elapsed second(s) elapsed.\n";

        1.49982798099518 second(s) elapsed.

• Time::HiRes is also available from CPAN

• It also provides high-resolution versions of sleep and alarm

  • Also other high-resolution time-related functions
