Bug description:Incorrect / misleading description of the ISO-8601 week-numbering year
Description:
------------
---
From manual page: http://www.php.net/function.date
---
The explanation for the date format specifier o is as follows:
> ISO-8601 year number. This has the same value as Y, except that if the
ISO week number (W) belongs to the previous or next year, that year is
used instead. (added in PHP 5.1.0)
That seems misleading. o is used as the _ISO week-numbering year_
which is different from the normal year that ISO-8601 uses. Unless one
is using numbered weeks and day of the week to represent a date, the
regular year is ISO-8601 compliant. However, calling this the "ISO-8601
year number" makes it seem like those who wish to conform to ISO-8601
should use o, which is incorrect.
