DateTimeOffset.Subtraction Operator (DateTimeOffset, TimeSpan)

Subtracts a specified time interval from a specified date and time, and yields a new date and time.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static DateTimeOffset operator -(
	DateTimeOffset dateTimeOffset,
	TimeSpan timeSpan
)

Parameters

dateTimeOffset
Type: System.DateTimeOffset

The date and time object to subtract from.

timeSpan
Type: System.TimeSpan

The time interval to subtract.

Return Value

Type: System.DateTimeOffset
An object that is equal to the value of dateTimeOffset minus timeSpan.

ExceptionCondition
ArgumentOutOfRangeException

The resulting DateTimeOffset value is less than MinValue or greater than MaxValue.

The Subtraction method defines the subtraction operation for DateTimeOffset objects. It enables code such as the following:

DateTimeOffset offsetDate = new DateTimeOffset(2007, 12, 3, 11, 30, 0, 
                               new TimeSpan(-8, 0, 0)); 
TimeSpan duration = new TimeSpan(7, 18, 0, 0);
Console.WriteLine(offsetDate - duration);  // Displays 11/25/2007 5:30:00 PM -08:00

Languages that do not support custom operators and operator overloading can call the DateTimeOffset.Subtract(TimeSpan) method instead.
