/*
 *  Name:           setMetricsData
 *  Input:          Metrics structure
 *  Output:         Metrics structure
 *  Return:         void
 *  Description:    This routine sets two values for laster metric collection.  
 *                  The first is specific to the individual command being 
 *                  processed and sets the lastTimeMark field for that command 
 *                  metric structure.  The second value set is the command type 
 *                  for later update which is stored in the lastCommand filed of
 *                  the input Metric structure.  If a command type is passed 
 *                  which is not recognized, it sets the lastCommand field to
 *                  INVALID.
 *  Calls:          getTime()
 *      System:
