Any good lightweight date/time picker for web with good UI?

Question

A few wishes:

• If it is jQuery based, best.
• If it focuses on easy UI rather than eye candy, better.
• If it is both a date and time picker, good.

Answer 1

Datepicker:

jQuery UI Datepicker

Timepicker:

timepickr plugin

Bonus points, both use the jQuery UI Themeroller.
