Any ideas how I can get to use usleep to work?
I try 

use TIME::HiRes qw(usleep time alarm sleep);

$nightpause=(2000);

$time=localtime;
if ($time=~/(\d+?):\d+?:\d+?/) {
    $hour=$1;
}
if ($hour<=6 or $hour>=17) {
    usleep ($nightpause);
}

and I get a complaint that usleep is an undefined subroutine!
