Hi All,
I have a hard time figuring out what really is that ISO-8601 year format and what its purpose is. Third party applications that we use (Drupal, Solr...) would tell you to configure the date format using an ISO-8601 year like 'd-m-o' instead of 'd-m-Y'.
Then all the sudden we are the 30rd of December 2013 and all my websites would display dates as 30-12-2014 . I guess this makes kind of sense reading the php manual:
"if the ISO week number (W) belongs to the previous or next year, that year is used instead".
But I'm neither sure why the iso week number belongs to 2014 or how this format could be usefull since dates are just formatted wrong.
Anyone to help me understand this mess ?
Thanks
