Time data B is formatted as shown below.
Time data A is formatted as shown below.
If the operation result exceeds any of the data ranges given above, time data A is not updated, the seconds data is set to
9,999, and the status bit is set to 1 (ON).
If the operation result is within the ranges, the status bit is set to 0 (OFF).
A year is calculated as 365 days. Leap years are not supported.
The number of months is not calculated. Only the number of days is calculated.
