The Subtraction(DateTime, DateTime) method does not consider the value of the Kind property of the two DateTime values when performing the subtraction. Before subtracting DateTime objects, ensure that the objects represent times in the same time zone. Otherwise, the result will include the difference between time zones.

The DateTimeOffset.Subtraction(DateTimeOffset, DateTimeOffset) method does consider the difference between time zones when performing the subtraction.
