The TIMESTAMP data type is used to store a point in time containing year, month, day, hour, minute, second and fraction of a second.
The fraction is stored to 6 decimal places. A TIMESTAMP value requires 8 bytes of storage.
Although the range of possible dates for the TIMESTAMP data type is the same as the DATE type (covering years 0001 to 9999), the useful range of TIMESTAMP date types is from 1600-02-28 23:59:59 to 7911-01-01 00:00:00. Prior to, and after this range the time portion of the TIMESTAMP may be incomplete.
