initialize initializes the metronome to start from the given start time.

loop period (ns) sets the loop control rate.

start time (ns) sets the start time for the first iteration of the calling loop structure. If the start time is zero, the first iteration will begin on the next loop rate boundary. For example, with a start time of zero and a loop rate of one second (1,000,000,000 ns), the metronome will begin on the next second's boundary.

finished late? is TRUE if the previous loop iteration finished late.

time snapped event is TRUE if a discontinuity in time has occurred. Provide a new start time and set the initialize terminal to TRUE.
