DateTimeOffset Constructor (DateTime)

Initializes a new instance of the DateTimeOffset structure using the specified DateTime value.

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

public DateTimeOffset(
	DateTime dateTime
)

Parameters

dateTime
Type: System.DateTime

A date and time.

ExceptionCondition
ArgumentOutOfRangeException

The Coordinated Universal Time (UTC) date and time that results from applying the offset is earlier than MinValue.

-or-

The UTC date and time that results from applying the offset is later than MaxValue.

This constructor's behavior depends on the value of the DateTime.Kind property of the dateTime parameter:

The following example illustrates how the value of the DateTime.Kind property of the dateTime parameter affects the date and time value that is returned by this constructor.

DateTime localNow = DateTime.Now;
DateTimeOffset localOffset = new DateTimeOffset(localNow);
Console.WriteLine(localOffset.ToString());

DateTime utcNow = DateTime.UtcNow;
DateTimeOffset utcOffset = new DateTimeOffset(utcNow);
Console.WriteLine(utcOffset.ToString());

DateTime unspecifiedNow = DateTime.SpecifyKind(DateTime.Now, 
                               DateTimeKind.Unspecified);
DateTimeOffset unspecifiedOffset = new DateTimeOffset(unspecifiedNow);
Console.WriteLine(unspecifiedOffset.ToString());
// 
// The code produces the following output if run on Feb. 23, 2007, on 
// a system 8 hours earlier than UTC: 
//   2/23/2007 4:21:58 PM -08:00 
//   2/24/2007 12:21:58 AM +00:00 
//   2/23/2007 4:21:58 PM -08:00
