Returns a new DateTimeOffset object that adds a specified number of whole and fractional seconds to the value of this instance.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.Double
A number of whole and fractional seconds. The number can be negative or positive.
The fractional part of the seconds parameter is the fractional part of a second. The value of fractional parts of a second are shown in the following table.
The seconds parameter is rounded to the nearest millisecond.
This method returns a new DateTimeOffset object. It does not modify the value of the current object by adding minutes to its date and time.
Because a DateTimeOffset object does not represent the date and time in a specific time zone, the method does not consider a particular time zone's adjustment rules when it performs date and time arithmetic.
