A1SD51S/AD51H-S3 QD51(-R24)
Countermeasure
Reading
Reads only the last two digits of the year.
However, if the last two digits are 90 or
more, the first two digits are 19. If the last
two digits are less than 90, the first two
digits are 20.
Reads the four-digit
year as it is.
Modify the program to
use four-digit year
processing.
Writing
Writes only the last two digits of the year.
Writes the four-digit
year as it is.
Designate the year as
four digits correctly.
