This application plays the sounds of a ships clock every hour and half hour. The sequence is identical to ships bells, which are used to regulate sailors duty watches. Unlike a regular clock, the chimes do not correspond to the number of the hour. Instead, there are eight bells, one for each half hour of a four-hour watch.
This version will cause the chimes to strike continuously until the chimes are turned off and does not have to be running for the chimes to strike.
