3. EXPLANATION OF MESSAGE

   The system will make an entry on the AMA tape, showing the old and 
   corrected times, and also print the corrected time via the TTY.

   a =   Two-digit number (01-12) for the month.

   b =   Two-digit number (01-31) for the day of the month.

   c =   Four-digit number of the year.

   d =   Day of the week (SUN, MON, TUE, WED, THU, FRI, or SAT).

   e =   Two-digit number (00-23) identifying the hour of the day.

   f =   Two-digit number (00-59) for the minutes after the hour.

   g =   Two-digit number (00-59) for the seconds after the minute.

4. SYSTEM RESPONSE

   OK =  Indicates that clock is being set.  Followed by corrected 
         time of day.

   NG =  Indicates that input limit of 'e', 'f', or 'g' is 
         exceeded.

                              CAUTION

                     1) Verify that correct time and
		        date have been input in the
			TTY message.
	             2) Never span the midnight hour
		        in either direction.  An advance
			through midnight will inhibit
			the midnight routines and no
			AMA header will be generated
			for the required data change.
			A CLK-SET back through the
			midnight hour will repeat the
			midnight routines and advance
			the date a second time.
		     3) Observe restricted hours.
		     4) Do not make minor adjustments
		        between 2300 hours and midnight.
			Such changes prevent the proper
			billing of all calls affected
			by the time change and held
			through midnight.
