7.15.4 Clock data subtraction operation (DATE-(P))
DATE-(P)
Function
(1) Subtracts the time data designated by from the clock data designated by , and stores
the result into the area starting from the device designated by .
For example, if the clock time 3:50:10 were subtracted from the clock time 10:40:20, the
operation would be performed as follows:
(2) If the subtraction results in a negative number, 24 will be added to the result to make a final

For example, if the clock time 10:42:12 were subtracted from 4:50:32, the result would not
be 6:8:20, but rather would be 18:8:20.
Remark
See 7.15.2 for further information regarding the data that can be set for hours,

: Head number of the devices where the clock time data to be adjusted by substraction is stored (BIN 16 bits)
: Head number of the devices where time data to be subtracted for adjustment is stored (BIN 16 bits)
: Head number of the devices where the result of subtraction of clock (time) data will be stored (BIN 16 bits)
