Ship's Clock 2.0

The Ships Clock application will ring a bell on every half-hour in the style of the standard ship's clock. That standard has its roots in centuries of sailing ships around the world where clocks were impractical and is still used in present-day navies. It is based on four-hour watches: each watch was on duty for four hours starting at the hour of 12, 4, or 8 (am or pm).
