.NET Time Zone Information

Question

What is the standard format for datetime with timezone in an ASP.NET ASP.NET application?

Updated to clarify: in ASP.NET, I need to check the datetime from a Domino database with a .NET DateTime. The client asks what will be the best format in which he must provide the date and time with the time zone. So which format is the most readable .NET?

Assuming you meant a string from a DateTime object, the easiest way would be to use DateTime.Parse("MM/DD/YY HH:mm:ss UTC-OFFSET"), for example, "03/01/2009 05:42:00 -5: 00". For more information, see the Parse documentation .
