Need Date/Time Picker with specific functions

_x000D_ _x000D_ I've looked around, and I do see previous questions where people ask about Date/Time pickers; unfortunately none of those threads matched my specific needs. I see a lot of people recommending Any+Time as well, but it seems a little "heavy" and I'm looking for lightweight. Basically, I have the need for a date/time picker for "events". The event-search picker here (http://jqueryui.com/demos/datepicker/#event-search) is very nice, but it doesn't handle time. My form is built on jQuery, so I'm okay with using that. Must be able to select both date and time End time form should be hidden until the start time is selected. After the start time is selected, end time should automatically be set for 6 hours later Should not be able to select an end time that takes place before the start time Should be able to handle timezones, and default to the user's current timezone Should be able to send out a UTC timestamp (I will store in a hidden field; ex: 1291004863) Your recommendations are appreciated... I dont know much about Javascript.
