Hello Monks,

I want to store times (hours, minutes, seconds, fractions of a second) in an object. Time::Piece and Time::Seconds make a good beginning. They offer some arithmetic operations and have overloaded >, <, ... .

The following code uses Time::Seconds and Time::Piece to construct the sum of "16:51" and "34:48" in the format (min:sec).

#!/usr/bin/perl

use strict;
use warnings;

use Time::Piece;
use Time::Seconds;

my $t1 = Time::Piece->strptime("16:51", "%M:%S");
my $t2 = Time::Piece->strptime("34:48", "%M:%S");

$t1 += $t2->min*60 + $t2->sec;

print $t1->strftime("%M:%S");

But there are two reasons why they are not sufficient for what I want to do.

  1. I need a fraction of a second (e.g. "16:51,12" and "34:48,14"). I did not found fraction for strftime or strptime.
  2. I want to be able to use more arithmetic operations with these time objects. For example: ($t1 * 4) + $t2

Here the summary: I would like to have a parse function (time string e.g. "16:51,14" to time object). It should be possible to apply arithmetic operations and comparisons of time objects and the time object should at least store hours, minutes, seconds and fractions of a second. And of course I want to be able to print the time object (something like strftime).

Is there already a module in CPAN which can do this? I did not find any. What would you suggest how to solve that? I don't want to reinvent everything. If possible I want to use an available module.

I'm very interested in your answers.

Thank you and Greetings

Dirk
