Time2

When the time2.N.start bit goes true the cycle timer resets and starts
to time2 until time.N.start goes false. If you connect time2.N.start to
halui.is-running as a cycle timer it will reset during a pause. See
the example connections below to keep the timer timing during a pause.

Time2 returns the hours, minutes, and seconds that time2.N.start is true.

The cumulative total is displayed by the second set of pins

Sample pyVCP code to display the hours:minutes:seconds.
