Quick tip: clone of PHP’s microtime() function as a Perl subroutine.

Refer to the PHP manual for how the function is supposed to work. The short version is that you call “microtime(1)” to get this perl subroutine to return a float-formatted value containing the seconds and microseconds since the unix epoch.

	# Clone of PHP's microtime. - from http://seancolombo.com
	use Time::HiRes qw(gettimeofday);
	sub microtime{
		my $asFloat = 0;
		if(@_){
			$asFloat = shift;
		}
		(my $epochseconds, my $microseconds) = gettimeofday;
		if($asFloat){
			while(length("$microseconds") < 6){
				$microseconds = "0$microseconds";
			}
			$microtime = "$epochseconds.$microseconds";
		} else {
			$microtime = "$epochseconds $microseconds";
		}
		return $microtime;
	}
