Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public DateTimeOffset AddSeconds(
	double seconds
)

Parameters

seconds
Type: System.Double
A number of whole and fractional seconds. The number can be negative or positive.

Return Value

Type: System.DateTimeOffset
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.

ExceptionCondition
ArgumentOutOfRangeException

The resulting DateTimeOffset value is less than MinValue.

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.

NoteNote:

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.
