so... is there a difference between "not changing the timestamp" or
"preserve" what should be the correct timestamp? Just fooling with
your choice of words. As far as I see, "something that makes a
modification without changing the timestamp" would only do it for the
reason that it thinks that is the correct timestamp. And yes, those
tools are a threat.
Otherwise you are not saying anything different than me, so I agree.

I'm puzzled whether you are trying to disagree or what.
Certainly if you replace a file from a zip then you are replacing with
an older version, so it makes sense the date is older. Subversion
only uses the timestamp to detect if the file might have changed, and
in the case of restoring an old version from zip, it likely has. So
what's your point? Someone said it detects the older timestamp as
being a change (no reason not to), therefore no problem.

Not even the same thing--Subversion does not need to compare
timestamps with the repository, only with the local "pristine copy".
This talk of moving the working copy to another system is risky, and
outside the scope of subversion.
Suggestion: Don't set time different on *any* two relative machines
(what would even be the purpose), esp. if you plan to use version
control between the two.
The big problem is inconsistency when keeping track of time. The only
solution really is to stay consistent. Anything else is only a
workaround.
