A number of whole and fractional seconds. The value parameter can be negative or positive.
Return ValueType: System.DateTime
An object whose value is the sum of the date and time represented by this instance and the number of seconds represented by value.
The fractional part of value is the fractional part of a second. For example, 4.5 is equivalent to 4 seconds, 500 milliseconds, and 0 ticks.
The value parameter is rounded to the nearest millisecond.
The following example uses the method to add 30 seconds and the number of seconds in one day to a DateTime value. It then displays each new value and displays the difference between it and the original value. The difference is displayed both as a time span and as a number of ticks.
