/*  Task_1_through_3
 *
 *  This task is a cyclic version of test1 to asssure that the times
 *  displayed are not skewed as in test1.  "TA1" is printed once every
 *  5 seconds, "TA2" is printed once every 10 seconds, and "TA3" is
 *  printed once every 15 seconds.  The times displayed should be
 *  in multiples of 5, 10, and 15 for TA1, TA2, and TA3 respectively.
 *  If the times are skewed from these values, then the calendar time
 *  does not correspond correctly with the number of ticks.
