Examples

The following example shows how to initialize a DateTimeOffset object with a date and time and the offset of the local time zone when that time zone is not known in advance.

Dim localTime As Date = #7/12/2007 6:32:00 AM#
Dim dateAndOffset As New DateTimeOffset(localTime, _
                         TimeZoneInfo.Local.GetUtcOffset(localTime))
outputBlock.Text &= dateAndOffset.ToString() & vbCrLf
' The code produces the following output:
'    7/12/2007 6:32:00 AM -07:00
DateTime localTime = new DateTime(2007, 07, 12, 06, 32, 00);
DateTimeOffset dateAndOffset = new DateTimeOffset(localTime,
                         TimeZoneInfo.Local.GetUtcOffset(localTime));
outputBlock.Text += dateAndOffset + "\n";
// The code produces the following output:
//    7/12/2007 6:32:00 AM -07:00
