That's fine if your application imposes such restrictions, but it is not what ISO 8601 requires. ISO 8601 fixes some notations but it does not constrain Mon, 01 Jun 2009 02:57:31 GMT piebaldconsult http://tech.groups.yahoo.com/group/ISO8601/message/2197 http://tech.groups.yahoo.com/group/ISO8601/message/2197 ...
