[pve-devel] [PATCH access-control 3/3] ticket: add comments about auth key mtime

[Fabian Grünbichler]

we cannot fully close this window, and don't need to anyway since we
apply +-300s when calculating ticket age ranges, but documenting where
mtime is used and what we expect seems like a good idea for future
readers.
