A clock or watch is a device used to measure, keep, verify, and indicate team. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units. As shown in the image below, the clock diagram can be used to illustrate how time is spent or the sequence of events in a story. In making a clock diagram, a teacher or a clock designer, the student must identify the main events in the cycle, how one event leads to another, and if appropriate, how the cycle repeats. A clock diagram can be built using EdrawMax and customize it as per the requirement.
