Implement new date / time plugin

Hi,

As discussed in the adv group, I'm starting to dump some usability issues. Can you create a component or type of issue or however you think it's best so that's easier to spot them ?

Anyway, for the calendar

1) jquery ui has a date picker
http://docs.jquery.com/UI/Datepicker

2) I've used pretty date to format the display (eg tomorrow, in 4 hours... Makes it nicer (I'll commit for a "calendar" exemple)

3) One field where you can type directly 10/10/09 is way easier to use than the selects

4) Allow to add "humane" formats as input too

5) Potential candidate to use:

6) Also evaluate: http://milesich.com/timepicker/ (It is extension UI datepicker)

Another time picker:
