• These instructions add the time data in the device specified by (s2) to the time data in the device specified by (s1), and
store the addition result in the device number specified by (d) and later.
(s1) hour (0 to 23)
(s1)+1 minute (0 to 59)
(s1)+2 second (0 to 59)

• If the time obtained as the result of addition exceeds 24 hours, 24 hours are subtracted from the resultant time to produce
the operation result. For example, when 20:20:20 is added to 14:20:30, the operation result is 10:40:50 rather than
34:40:50.
