Question: What is date type in C?

What data type is date in C?

The c-tree date field stores date as an unsigned 4 bytes integer value representing the number of days since 02/28/1700. Hence the first valid date is 03/01/1700. A check is done to limit the date range lower bound to 03/01/1700 in case of a c-tree Plus date type and 01/01/1900 for the FairCom DB SQL TIMESTAMP type.
