What library can I use to calculate dates based on date expressions?

A date expression would be something like:

"+3D" (plus three days)
"-1W" (minus one week)
"-2Y+2D+1M" (minus 2 years, plus one day, plus one month)

Example:

DateTime EstimatedArrivalDate = CalcDate("+3D", DateTime.Now);

Where estimated arrival date would equal the current date plus 3 days.

I have heard about JodaTime and NodaTime but I have not seen anything in them yet that does this. What should I be using to get this functionality in C#?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy.
