Telerik has a graphical timepicker control that we're using on desktop applications (WinForms). We'd like something similar for web-apps deployed to our intranet/extranet. The essential features for us are the AM|PM toggle; the display of the 12 hours in several columns and the ability of the developer to define/limit the minutes interval (e.g. 15, 30, 45, 00) in the bottom pane. We are using 15-minute intervals and so the current Kendo dropdown-list timepicker would have to contain 96 items. The Telerik visual approach avoids a long scrolling list:
