.... here is this old code from someone..... it should show you how to fish 
#!/usr/bin/perl
#seconds to #d_HH:MM:SS.ss and back.

#constants
my $m = 60;
my $h = 60 * $m;
my $d = 24 * $h;

#example
print s2dhms(86000),"\n";
print dhms2s('23:53:20'),"\n";


sub dhms2s {
       my $dhms = shift;
       my @dinfo = split /d_|:/, $dhms;
       my ($s, $m, $h, $d) = reverse @dinfo;
       $d ||= 0;
       $h ||= 0;
       $m ||= 0;
       return (
         (( $d * 24  + $h ) * 60  + $m ) * 60  + $s
       );
}

sub s2dhms {
       my $secs = shift;
       my $D = int($secs / $d); $secs = $secs - $D * $d;
       my $H = int($secs / $h); $secs = $secs - $H * $h;
       my $M = int($secs / $m); $secs = $secs - $M * $m;
       my $S = $secs ;
       my $r;
       if ($D) {
               $r .= sprintf "%dd_", $D;
       }
       if ( $S == int $S ) {
               $r .= sprintf "%02d:%02d:%02d", $H, $M, $S;
       } else {
               $r .= sprintf "%02d:%02d:%05.2f", $H, $M, $S;
       }
       return $r;
