A number of whole and fractional milliseconds. The value parameter can be negative or positive.

Remarks

This method does not change the value of this DateTime. Instead, a new DateTime is returned whose value is the result of this operation.

The fractional part of value is the fractional part of a millisecond. For example, 4.5 is equivalent to 4 milliseconds, and 5000 ticks (where one millisecond = 10000 ticks).

The value parameter is rounded to the nearest tick.
