High Quality Content by WIKIPEDIA articles! A time signal is a visible, audible, mechanical, or electronic signal used as a reference to determine the time of day. One sort of public time signal is, of course, a striking clock. These clocks, however, are only as good as the clockwork that activates them; they have improved substantially since the first surviving clocks from the fourteenth century. For many members of the general public, a public clock such as Big Ben was the only time standard they needed.
