Bug description:  date gives 0 as a week number of year

I found out that date("W", $stamp) can gives a zero as output.


<?php
$stamp = time();

while( date("W", $stamp ) != 0 )
        $stamp+=5000;

print date( "d.m.Y H:i W", $stamp ) . " $stamp\n";
?>

Out could be for examble "01.01.2005 00:46 0 1104533193".


I check the ISO-8601 standard (version 2000-12-19
ISO/TC 154 N 362) and it says:

calendar week is represented by two decimal digits. The first calendar
week of a year shall be identified as
[01] and subsequent weeks shall be numbered in ascending sequence.

Futhermore the date function should have a option for 'normally' week
number of the year like most of people does it understand practically:
1.1.xxxx is 1 and so on and finally 31.12.xxxx is 52.
