I want to speak to a soap service that has a date parameter which is required to be the CCYYMMDD format.
CCYYMMDD
What is its definition?
It's just another way of writing yyyyMMdd.
yyyyMMdd
The CC part represents the century, while YY is the two-digit year.
CC
YY
So instead of having year 2014, you can use century 21, year 14
yyyy CC YY 2014 -> 21 14
