Accessing the reflog remotely

Hi,

I guess the answer is "no", but I'll still ask in case ...

Is it possible to access the reflog of a remote repository other than
logging into this repository?

My use-case is the following: I want to checkout "the last revision
pushed in master on ssh://host/repo/ on day D at midnight" (to fetch
the project of my students ;-) ). If it were locally, I'd do

  git checkout 'origin/master@{Nov 3 00:00:00}'

But this tells me where _my_ local master was on that date (i.e. the
last revision I had pulled).


So, the best I can think of is:

ssh host 'cd /repo/ ; git tag final-version "master@{Nov 3 00:00:00}"'
git fetch --tags
git checkout tags/final-version

Is there a better way?

Thanks,
