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


Type: System.DateTime

A date and time.


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


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);

DateTime utcNow = DateTime.UtcNow;
DateTimeOffset utcOffset = new DateTimeOffset(utcNow);

DateTime unspecifiedNow = DateTime.SpecifyKind(DateTime.Now, 
DateTimeOffset unspecifiedOffset = new DateTimeOffset(unspecifiedNow);
// 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
