7.25 Clock Instructions
Processing details
• These instructions subtract the time data in the device specified by (s2) from the time data in the device specified by (s1),
and store the subtraction result in the device number specified by (d) and later.
Ex.
3:50:10 is subtracted from 10:40:20.
• If the time obtained as the result of subtraction becomes a negative value, 24 hours are added to the resultant time to
produce the operation result. For example, when 10:42:12 is subtracted from 4:50:32, the operation result is 18:8:20 rather
than -6:8:20.
