Answer 1

I think you want DateTime.Now.ToString("r") ,
where the 'r' indicates formatting following the RFC1123 pattern.

It will not (always) display an offset as +000, it will use 'GMT' and other standardized tz names.

As far as I can tell this one of the rare case where you don't have to specify an IFromatProvider.
