You found a bug in NFSv4.n when delegations are enabled (nfscbd
running on the client and a server that has delegations enabled).
I reproduced it. The mtime is actually correct on the file server.
(if you look at the files on the server after unrolling the tarball.)
At least this is what I see.
However, the client is returning a stale mtime.
Since I can reproduce it, I should be able to fix it fairly quickly.
You already know how to avoid it (don't run nfscbd or don't enable
delegations on the server).
Thanks for reporting it, rick
ps: It would still be nice if you can answer the questions in my
previous email.
