Adds a specified number of whole and fractional minutes to the current DateTimeOffset object.
An object whose value is the sum of the date and time represented by the current DateTimeOffset object and the number of minutes represented by minutes.
The fractional part of the minutes parameter is the fractional part of a minute. For example, 4.5 is equivalent to 4 minutes, 30 seconds, 0 milliseconds. The minutes parameter is rounded to the nearest millisecond.
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 DateTimeOffset.AddMinutes(double) method does not consider a particular time zone's adjustment rules when it performs date and time arithmetic.
Converting time intervals of less than a minute to a fraction can involve a loss of precision. (For example, one second is 0.01666 of a minute.) If this is problematic, you can use the DateTimeOffset.Add(TimeSpan) method, which enables you to specify more than one kind of time interval in a single method call and eliminates the need to convert time intervals to fractional parts of a minute.
