Comment:

 I was able to reproduce this issue: I got responses with `max-age=2400`
 and an `Age` going up from `0` to `2405` depending on when I made the
 request.  After that last response I got a new response with `Age`
 starting at `0` again.

 But unless this breaks clients somehow, which I assume is not the case, I
 don't think this is worth investigating.  We only run into this case at
 most once every 5 minutes per requested resource and for all clients
 requesting that resource.  It's cheaper to provide more caching resources
 than hunt down and fix this bug.  It's not even clear that this is a bug
 in the Java part of Onionoo or in the specific Varnish configuration used
 here.  It might be a Varnish bug.  But who knows.

 I'm closing this ticket.  Feel free to re-open this ticket if this issue
 breaks clients.  And thanks for reporting anyway!
