A time picker for jQuery. table version | list version. Requires below plugin for correct positioning. There is also another version (not by me) that has a few extra features and a demo of it working with the datePicker plugin.
Source code available from GitHub or a Zipped download.
Default $('#mytime').timePicker()
Custom $('#mytime15').timePicker({step: 15, startTime: "11:35", endTime: "16:00", columns: 5}), 15 minute steps, starting at 11:35, ending at 16:00, 5 columns
Still needs work.
