DateTimeOffset.AddMinutes Method

Adds a specified number of whole and fractional minutes to the current DateTimeOffset object.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
public DateTimeOffset AddMinutes(
	double minutes
)

Parameters

minutes
Type: System.Double

A number of whole and fractional minutes. The number can be negative or positive.

Return Value

Type: System.DateTimeOffset
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.
ExceptionCondition
ArgumentOutOfRangeException

The resulting DateTimeOffset value is less than MinValue.

-or-

The resulting DateTimeOffset value is greater than MaxValue.

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.

NoteNote

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.
