DateTimeOffset.AddMilliseconds(Double) Method
Important

Returns a new DateTimeOffset object that adds a specified number of milliseconds to the value of this instance.
public:
DateTimeOffset AddMilliseconds(double milliseconds);
public DateTimeOffset AddMilliseconds (double milliseconds);
member this.AddMilliseconds : double -> DateTimeOffset
Public Function AddMilliseconds (milliseconds As Double) As DateTimeOffset
- milliseconds
- Double
A number of whole and fractional milliseconds. The number can be negative or positive.
An object whose value is the sum of the date and time represented by the current DateTimeOffset object and the number of whole milliseconds represented by milliseconds
.
The resulting DateTimeOffset value is less than DateTimeOffset.MinValue.
-or-
The resulting DateTimeOffset value is greater than DateTimeOffset.MaxValue.
The fractional part of the milliseconds
parameter is the fractional part of a millisecond. For example, 4.5 is equivalent to 4 milliseconds and 5000 ticks, where one millisecond equals 10,000 ticks. However, in .NET 6 and earlier versions, milliseconds
is rounded to the nearest millisecond, and all values of .5 or greater are rounded up. In .NET 7 and later versions, the full Double precision of the milliseconds
parameter is used. However, due to the inherent imprecision of floating point math, the resulting precision will vary.
Note
This method returns a new DateTimeOffset object. It does not modify the value of the current object by adding milliseconds
to its date and time.
Because a DateTimeOffset object does not represent the date and time in a specific time zone, the AddMilliseconds method does not consider a particular time zone's adjustment rules when it performs date and time arithmetic.
