    Because SQL datetime has lower resolution.

    The DateTime data type in MS SQL
    represents Date and time data from
    January 1, 1753, to December 31, 9999,
    with an accuracy of one
    three-hundredth second, or 3.33
    milliseconds. Values are rounded to
    increments of .000, .003, or .007
    milliseconds.

    Anno Domini (Common Era) through
    11:59:59 P.M., December 31, 9999 A.D.
    (C.E.) Time values are measured in
