ok I have some problems with test values here now, but I can provide the
original phpgw code
that is affected and the values from it:
$sday = mktime(2,0,0,$month,$day - ($weekday - 1),$year);
echo ':' . $day . ':' . $weekday . "
\n";
echo ':' . $year . '/' . $month . '/' . ($day - ($weekday - 1)) . ' : ' .
$sday . ":
\n";
Output values here 32bit linux machine:

The complete function within this code was found is:
function get_weekday_start($year,$month,$day)
{
$weekday = $this->day_of_week($year,$month,$day);
switch($GLOBALS['phpgw_info']['user']['preferences']['calendar']['weekdaysta
rts'])

// Saturday is for arabic support
case 'Saturday':
$this->days = Array(
0 => 'Sat',

break;

mktime(2,0,0,$month,$day,$year);

$sday = mktime(2,0,0,$month,$day -

after I changed this code by the following patch, it works as expected on
both platforms:
