Answer 1

You shouldn't be converting the DateTime to a string and back - but your current problem is that you're converting the UTC value you get back from the server into a local DateTime for no obvious reason. Ideally, I'd suggest changing GetFastestNISTDate() to return an Instant, but assuming you can't do that:

• Don't do the parsing yourself. Take the appropriate substring from the response, then use DateTime.ParseExact, specifying CultureInfo.InvariantCulture and DateTimeStyles.AssumeUniversal
• Don't convert the UTC DateTime to a local version - it's pointless and confusing
• Use Instant.FromDateTimeUtc to convert a UTC DateTime to an instant

The final part of your code (the last three lines) is okay, but why do you need a DateTime at all? If you can make as much of your code as possible use Noda Time, you'll get the greatest benefits in terms of code clarity.
