However, if I use one of the formats that start with 'D', the hour doesn't overflow to the next day, but to the next (e.g.) *Monday* (i.e. same weekday of the next week): Test script: --------------- var_dump(DateTime::createFromFormat(DateTime::RFC822, 'Mon, 3 Aug 20 25:00:00 +0000')); var_dump(DateTime::createFromFormat(DateTime::RFC1036, 'Mon, 3 Aug 20 25:00:00 +0000')); var_dump(DateTime::createFromFormat(DateTime::RFC1123, 'Mon, 3 Aug 20 25:00:00 +0000')); var_dump(DateTime::createFromFormat(DateTime::RFC7231, 'Mon, 3 Aug 20 25:00:00 GMT')); var_dump(DateTime::createFromFormat(DateTime::RFC2822, 'Mon, 3 Aug 2020 25:00:00 +0000')); var_dump(DateTime::createFromFormat(DateTime::RSS, 'Mon, 3 Aug 2020 25:00:00 +0000')); Expected result: ---------------- 4 Aug 2020 01:00 Actual result: -------------- 10 Aug 2020 01:00 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79926&edit=1
