2.2.7.5 Sample Flow of Time Measurement by Sequencer

In the following sample, when events are executed in the order of Event 1, Event 2 and

Event 3, the execution time from the Event 1 to the Event 3 is measured. However, no

measurement is made if Event 4 occurs anywhere between Event 1 and Event 3.
