Definition
Returns a new DateTimeOffset object that adds a specified number of whole and fractional seconds to the value of this instance.
public:
DateTimeOffset AddSeconds(double seconds);public DateTimeOffset AddSeconds (double seconds);member this.AddSeconds : double -> DateTimeOffsetPublic Function AddSeconds (seconds As Double) As DateTimeOffsetParameters
- seconds
- Double
A number of whole and fractional seconds. The number can be negative or positive.
Returns
An object whose value is the sum of the date and time represented by the current DateTimeOffset object and the number of seconds represented by seconds.
Exceptions
The resulting DateTimeOffset value is less than MinValue.
-or-
The resulting DateTimeOffset value is greater than MaxValue.
Remarks
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.
| Second value | Equivalent |
|---|---|
| .1 second | 100 milliseconds |
| .01 second | 10 milliseconds |
| .001 second | 1 millisecond |
The seconds parameter is rounded to the nearest millisecond.
Note
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 AddSeconds method does not consider a particular time zone's adjustment rules when it performs date and time arithmetic.
