Returns a new DateTimeOffset object that adds a specified number of milliseconds to the value of this instance.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.Double
A number of whole and fractional milliseconds. The number can be negative or positive.
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, milliseconds is rounded to the nearest millisecond; all values of .5 or greater are rounded up.
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 method does not consider a particular time zone's adjustment rules when it performs date and time arithmetic.
