- A specific number of seconds. Note that the number in the val parameter can be either positive or negative, and it can express partial seconds as well as whole seconds.
This method does not change the value of the current DateTime object; rather, it returns a new DateTime object.
The fractional part of a second is represented by the fractional part of the val parameter. For example, 4.5 is equivalent to 4 seconds, 500 milliseconds, and 0 ticks. The number in the val parameter is rounded to the nearest tick.
