Strict cache expiration

[CMCDragonkai]

I am trying to cache an item with strict expiration. By this I mean that if I read and update an item the cache doesnt get a new expiration. Currently if I set an item that already exists I need to set a new expiration. However I want the item to continue with the same expiration. This is useful for caching OAuth access tokens.

This could be done in several ways. One could to allow the end developer to access the remaining expiration and exact expiration date so they can reset with a new remaining expiration time. But you can also add new methods to the item to facilitate this.

One thing though is that inserting an item with 0 as expiration. How would that work?

I've merged in a PR that should give you access to both the expiration and the creation time of the item. Does that help?

Which PR was that?

A more elegant manner would be a setting method that keeps the old expiration. Less work for everybody!
