how to read milliseconds with perl

[clarissa1996]

I need to calculate the elapsed time between two functions, in a perl program.

With the function localtime() I can read the current time. But the smaller unit is only seconds !

Is it possible to read a smaller time unit (for example milliseconds) ?


TIA Michelangelo Rezzonico

Here's a demo of Time::HiRes
________________________________________________________________________________
use Time::HiRes;

$ts= [Time::HiRes::gettimeofday];

$tp = Time::HiRes::tv_interval($ts, [Time::HiRes::gettimeofday]);
sleep(1);
$td = Time::HiRes::tv_interval($ts, [Time::HiRes::gettimeofday]);

print $tp, " ", ($td - $tp), " \r";
