Converts seconds into a formatted ddd:hh:mm:ss string. Nothing tricky, but I needed it. Critique welcome.

##
##  We assume $in_sec is a positive integer number of seconds.
##  Convert this to a 0-trimmed string of ddd:hh:mm:ss, 
##  or "days:hours:minutes:seconds". 
##

    my ($in_sec, $out_str, $out_m, $out_d, $out_h, $out_s);

    $in_sec=pop @ARGV;
    $hold_sec = $in_sec; 

    $out_d = int($in_sec / (3600*24));
    $in_sec = $in_sec % (3600*24);

    $out_h = int ($in_sec / 3600);
    $in_sec = $in_sec % 3600;

    $out_m = int ($in_sec / 60);
    $in_sec = $in_sec % 60;

    $out_s = $in_sec;

    if ($out_d > 0) {
        $out_str = sprintf "%u = %u:%0.2u:%0.2u:%0.2u\n", $hold_sec, $
+out_d, $out_h, $out_m, $out_s;
    } elsif ($out_h > 0) {
        $out_str = sprintf "%u = %0.2u:%0.2u:%0.2u\n", $hold_sec, $out
+_h, $out_m, $out_s;
    } elsif ($out_m > 0) {
        $out_str = sprintf "%u = %0.2u:%0.2u\n", $hold_sec, $out_m, $o
+ut_s;
    } else {
        $out_str = sprintf "%u = :%0.2u\n", $hold_sec, $out_s;
    }

     print $out_str;
