Date Compare
Compares Date 1 and Date 2, each rounded down to the nearest Date Part.
Return Value
If Date 1 (rounded down to the nearest Date Part) is less than Date 2 (rounded down to the nearest Date Part), the function returns -1. If Date 1 (rounded down to the nearest Date Part) is greater than Date 2 (rounded down to the nearest Date Part), the function returns 1. If Date 1 (rounded down to the nearest Date Part) equals Date 2 (rounded down to the nearest Date Part), the function returns 0.
For example, comparing 08/30/03 05:32 PM to 08/30/03 04:47 PM with Date Part set to m (for minute resolution) returns 1, while setting Date Part to d (for day resolution) causes this function to return 0.
