Operating system: all
PHP version: 5.0.4
PHP Bug Type: Date/time related
Bug description: Date('W') do not return leading zeros for week 1 to 9 (as
specified in ISO)
Description:
------------
The Date function have an ISO compilant Week parameter 'W'
This parameter should return leading zeros for week 1 to 9 (always
returning 2 digits).
Why
http://se.php.net/date :
> W ISO-8601 week number of year, weeks starting on Monday
> (added in PHP 4.1.0)
This week parameter do not return leading zeros when used like Date('W'),
Date('o\WW') etc. for the weeks 1 to 9
According to ISO 8601 weeks should be represented with leading zeros (from
section 4.8 Leading zeros
Each date and time component in a defined representation has a defined
length, and leading zeros shall be used as
required.) like:
Date - Week (extended format)
