Question

I’m trying to generate timestamp for cXML as shown below. Is there any function in C# which I can use to format date time to: 2011-06-09T16:37:17+16:37

e.g.

<cXML payloadID="[e-mail]"
timestamp="2011-06-09T16:37:17+16:37">

Use the “o” format specifier – read about this one in the standard Date and Time format strings documentation on MSDN.

The pattern for this specifier reflects a defined standard (ISO 8601).

And:

6/15/2009 1:45:30 PM -> 2009-06-15T13:45:30.0900000

string formatted = DateTime.Now.ToString("o");

If this is not what you want, you will need to use a custom format string – I believe you will need to do this, as the offset is not standard.

string formatted = DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ssK");
