Some quick perl to return the number of seconds in the current day since midnight.

sub midnight_seconds {
   my @time = localtime();
   my $secs = ($time[2] * 3600) + ($time[1] * 60) + $time[0];

   return $secs;
}

The same code just written in PHP.

function midnight_seconds() {
   $secs = (date("G") * 3600) + (date("i") * 60) + date("s");
   return $secs;
}
