3.12 Real Time Clock (RTC)
Note 1: The Christian era year column:
Note 2: Leap year:
3.12.1
3.12.2
This product has year column toward only lower two columns. Therefore the next year in 99 works
as 00 years. In system to use it, please manage upper two columns with the system side when
handle year column in the Christian era.
A leap year is the year which is divisible with 4, but the year which there is exception, and is divisible
with 100 is not a leap year. However, the year which is divisible with 400 is a leap year. But there is
not this product for the correspondence to the above exception. Because there are only with the
year which is divisible with 4 as a leap year, please cope with the system side if this function is
problem.
