【實用娛樂app】Ships Bells|最夯免費app-綠色工廠好玩App

This application plays the sounds of a ship's bell every hour and half hour. The strike of a ship's bell are used to regulate the sailors' duty watches. Unlike a regular clock, the strikes of the bell do not correspond to the number of the hour. Instead, there are eight bells, one for each-half hour of a four-hour watch.
