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.

Something like java.time.Period or datetime.timedelta would still be useful. Also (de)serializing RFC 3339/iso 8601 durations
