Returns a new DateTimeOffset object that adds a specified number of whole and fractional minutes to the value of this instance.
public:
DateTimeOffset AddMinutes(double minutes);public DateTimeOffset AddMinutes (double minutes);member this.AddMinutes : double -> DateTimeOffsetPublic Function AddMinutes (minutes As Double) As DateTimeOffsetParameters
- minutes
- Double
A number of whole and fractional minutes. The number can be negative or positive.
Returns
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.
Exceptions
The resulting DateTimeOffset value is less than DateTimeOffset.MinValue.
-or-
The resulting DateTimeOffset value is greater than DateTimeOffset.MaxValue.
Remarks
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.
In .NET 6 and earlier versions, the minutes parameter is rounded to the nearest millisecond. In .NET 7 and later versions, the full Double precision of the minutes 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 minutes to its date and time.
Because a DateTimeOffset object does not represent the date and time in a specific time zone, the AddMinutes 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 Add 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.
