The behavior is the same as for case 4. This case is to illustrate how the timing will be if the inhibit
time is longer than the event time.

SYNC
The SYNC producer broadcasts the synchronization object periodically. The SYNC message provides
the basic network synchronization mechanism. The time period between SYNC messages is specified
by the standard parameter communication cycle period. There may be a time jitter in transmission by
the SYNC producer corresponding approximately to the latency from some other message being
transmitted just before the SYNC.
