Edit report at https://bugs.php.net/bug.php?id=70115&edit=1 ID: 70115 User updated by: adambro at o2 dot pl Reported by: adambro at o2 dot pl Summary: DATE_ISO8601 const not compatible with ISO standard Status: Open Type: Documentation Problem Package: Documentation problem Operating System: N/A PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Expected result: Add a warning in documentation that DATE_ISO8601 is not compatible with that standard, hence other languages (Java, JS). Previous Comments: ------------------------------------------------------------------------ [2015-07-22 14:11:25] adambro at o2 dot pl Description: ------------ --- From manual page: http://www.php.net/class.datetime --- The constant DATE_ISO8601 is not compatible with ISO standard. The standard says in extended format (with colons) everything has to be in that notation, so having timezone represented as "+0000" (O in const string) is invalid. It should be "+00:00" (P in const). There's a #55272 bug, but it was closed due to wrong premise that basic format can be mixed with extended one. It is being explained in the comment already: http://php.net/manual/en/class.datetime.php#116085 Using date("c") yields correct format, also DATE_RFC3339 seem to be compatible. I've stumbled upon the bug while exchanging data with Java system. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70115&edit=1
