Need Duration to Represent Time in Months/Years

[codeslubber]

In reading around it seems that this was left out because years are not the same length nor are months.

The use case I am trying to support is a product that expires, or must be replaced, after 3 years. The precision is of course a non-issue in this use case. I am going to use the lifetime (Duration) to compute the Expiration by adding it to the Installation.

Yes I can just do it by multiplying types that are there.

It does seem that basic use cases should not be unexpressable.
