If you put a date in ISO format, you get an error, and the error doesn't even tell you what format is expected (see screenshot).
There should be a datepicker to relieve us from the guessing game, but it is broken:

Uncaught TypeError: init is undefined

We need to:
- accept date/time in iso format,
- tell the problem in the error message,
- repair the datepicker

All that without breaking existing date stored (so perhaps the iso date format will have to wait 7.0).
