Sure wish we could find a definition of what that field actually contains.  This seems intuitively correct.

// WHAT DOES THIS STRING MEAN?
$str = 'P2DT16H2M40S';


// GUESSING IT MEANS THIS:
// P = Pending
// 2D = Two Days
// T = Time
// 16H = Sixteen hours
// 2M = Two minutes
// 40S = Forty seconds

Look at the source code, it is written in javascript, if you need to convert it in php just say so.

You could use my suggestion from your last question, just change the words accordingly within the regex pattern.

Lukasz ChmielewskiCommented:
I guess I'd have to go with kaufmed's suggestion - use regex to convert.

I think we guessed right.  See "duration" on this page:
http://developer.ebay.com/devzone/merchandising/docs/callref/types/simpleTypes.html

Here is a slightly more comprehensive version, packaged as a function.  It does not cover the PnW or the Pdate formats, nor does it account for goofy things like fractional periods.
<?php // RAY_duration_strtotime.php
error_reporting(E_ALL);
date_default_timezone_set('America/New_York');


// WHAT DOES THIS STRING MEAN?
$str = 'P1Y3M2DT16H2M40S';

// IT IS THE ISO8601 FORMAT FOR A DURATION.
// SEE http://en.wikipedia.org/wiki/ISO_8601

// IT MEANS THIS:
// P   = Pending (INDICATOR OF ISO8601 DURATION)
// 1Y  = 1 Year
// 2M  = 2 Months
// 2D  = Two Days
// T   = Time Separator (M is ambiguous)
// 16H = Sixteen hours
// 2M  = Two minutes
// 40S = Forty seconds



// STRTOTIME CANNOT HANDLE ISO-8601 DURATIONS
$dur = strtotime($str);
var_dump($dur);
echo "<br/>";

// GET THE DURATION IN SECONDS FOR USE IN ARITHMETIC
$dur = duration_strtotime($str);
echo "<br/>" . number_format($dur) . ' SECONDS';

// USE THE DURATION IN ARITHMETIC
echo "<br/>" . date('r', strtotime("NOW + $dur SECONDS"));



// A FUNCTION TO MAKE A DURATION STRING INTO A NUMBER OF SECONDS
function duration_strtotime($str, $sho=FALSE)
{
    // REMOVE THE AMBIGUITY OF MONTH AND MINUTE -- MAKE MONTH = X
    $arr = explode('T', $str);
    $arr[0] = str_replace('M', 'X', $arr[0]);
    $new = implode('T', $arr);

    // EXPAND THE STRING INTO SOMETHING SENSIBLE
    $new = str_replace('S', 'seconds ', $new);
    $new = str_replace('M', 'minutes ', $new);
    $new = str_replace('H', 'hours ',   $new);
    $new = str_replace('T', ' ',        $new);
    $new = str_replace('D', 'days',     $new);
    $new = str_replace('X', 'months ',  $new);
    $new = str_replace('Y', 'years ',   $new);
    $new = str_replace('P', NULL,       $new);

    if ($sho) var_dump($new);

    // RETURN THE NUMBER OF SECONDS IN THE DURATION
    return strtotime($new) - strtotime('NOW');
}

Thanks for the points.  I had never seen the "duration" format before.  Very interesting question, ~Ray
