|Subject:||Not all specified formats validate|
These time formats listed as valid in the spec do not pass ISO8601TimeStr: hhmmss hhmm hh hh:mm These timezone offsets are listed as valid, but do not pass ISO8601DatetimeStrTZ: ±hhmm ±hh ENEEDMORETESTS! There's probably more. Need to go back to the spec and try them all. Also, push tickets/patches back into DateTime::Format::ISO8601 as needed.
