.01 second | 10 milliseconds |
.001 second | 1 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.
