How dates are stored

Dates containing year values are used internally and stored in Adaptive Server Anywhere databases using either of the following data types:

Data type	Contains	Stored in	Range of possible values
DATE	Calendar date (year, month, day)	4-bytes	0001-01-01 to 9999-12-31
TIMESTAMP	Time stamp (year, month, day, hour minute, second, and fraction of second accurate to 6 decimal places)	8-bytes	0001-01-01 to 9999-12-31 (precision of the time portion of TIMESTAMP is dropped prior to 1600-02-28 23:59:59 and after 7911-01-01 00:00:00)
