Hi fellow monks,

I'm having a problem with the sleep function in the Time::HiRes module in another script of mine so I quickly wrote the code below to test and this is what happens when I run it with sleep set to (0.001):

• I get roughly 1750 matches on my laptop
• If I run this on other laptops like mine I get the same results
• On a pair of Dells (one faster and one slower than my laptop) I get 0 matches
• If I compile the code with perl2exe(for this test only) and run it on my laptop I get 0 matches

Also if I run it with sleep set to (0.02) I get 0 matches on my laptop. So can the Monks explain why this is happening?

use strict;
use warnings;
use Time::HiRes qw(sleep gettimeofday tv_interval);

my $test  = 0;
my $match = 0;

while ( $test < 2000 ) {
    &sleepy($test);
    $test++;
}

print "A match occurred $match times";

sub sleepy {
    my $count = shift;
    my $time  = gettimeofday;
    sleep(0.001);    # Sleep here to ensure unique time
    my $hitime = gettimeofday;
    if ( $time == $hitime ) {
        $match++;
    }
}
