From Code Workshop:

Displays time intervals that span from as short as a second to as long as 24 hours. Graphically present any agenda or schedule. Perfect tool for meeting and conference planning. Customize your clock by inserting a logo, choosing colors, and specifying the fill pattern for each pie segment. The "drag and drop" feature allows you to place labels anywhere on the page without retyping.
