I thought I mentioned something about file timestamps not
guaranteeing file content. The date of a file is simply
the moment in time when it got placed onto the web server.
I'm not sure yum can even get that information, but if it
could, it would be useless. A repository is really just a
web page, and yum is just a wget with some control files
which tell it what to pull. So I don't think that yum's view
of a repository is quite what you think. The yum program
is very nice for what it does, and it does it very well.
It's very nice to use. I like it. It does some very clever
things. But due to the nature of what a repository is, I
don't see how yum could be used to accomplish the end you
have in mind. Even if it had access to file dates. And making
a repository contain the kind of information it would have
to have in order to accomplish your goal would take quite
a degree of co-operation among developers.

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
