I know it's really a separate issue, but this is yet another feature
that really needs to be enabled per-wc, or per-URL, not per-config.
We will probably get requests for it to be per-file as well.

How are files with local mods handled during switch/update? Does it
make a difference if the 3-way merge effectively causes the local mods
to disappear? Or causes a conflict?
What happens if the user provokes an MTIME_RECORD property conflict?

In past discussions I recall people assuming that mtime changes alone
would show up in status and cause a commit. Doing it the way you
propose is certainly simpler as it avoids all the questions about
timestamp resolution, status, etc., but I assume some users will be
What happens if the only local mod is an MTIME_RECORD property mod?
Is that a way of getting an mtime change committed?

What happens when something like svn:eol-style causes a file to get
rewritten after a commit completes? Does the mtime get set back even
though the content may have changed?

Even if the merge effectively causes local mods to disappear?
$ svn merge -cN
$ svn merge -c-N
What about a the merge only affects the MTIME_RECORD property -- should
such a merge update the mtime, update the property and so make the

Export currently sets mtime to commit time, why would it not use the
Why would revert not reset the mtime?
Lock/unlock will sometimes do mv/cp/rm in order to change permissions,
should they also set the mtime when doing that?

Overall it looks like you are proposing a "fragile" mtime in the
working copy, it is easy to "break" the mtime and there is little that
can be done to restore the versioned mtime short of an rm/up sequence.
That's merely an observation, I'm not claiming your proposed behaviour
