How dates are stored

Dates containing year values are used internally and stored in SQL 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 before 1600-02-28 23:59:59 and after 7911-01-01 00:00:00)
Note

When the precision of the TIMESTAMP is dropped, builtin functions that pertain to minutes or seconds will produce meaningless results.
