A structure that represents a date and time that can range in value from January 1, 1753 to December 31, 9999, with an accuracy of 3.33 milliseconds. This maps directly to the SQL Server datetime data type. It can also be used for the smalldatetime data type, which can store a date and time from January 1, 1900 to June 6, 2079 with an accuracy of one minute.
