Is there a tool out there that tells me which HSDir is/will probably be responsible for a given onion address (and at what time)?
There's no tool, unless you can reverse SHA1. (Or brute-force a set of popular onion addresses.)
I probably was not very clear in my question. I'm not aiming for the reverse path, just the normal calculation a tor client does given an onion address but instead of just calculating the current descriptor-id, print descriptor-ids for the future N days for onion address M (for the pre-prop224 world).
FYI https://gist.github.com/nogoegst/895dde228496e04f409fc6d160a5de5a
$ go run onion-desc-advance.go -time 1488288001 yrcfcqhja2ide7yh
prints descriptor IDs for the given time for replica #1 and #2.
