You cannot reset mtimes because Subversion never stores the mtimes.
You can change any revision's commit time (svn propset --revprop -r
123 svn:date <NEWDATE>) but that time then applies to all files
included in that revision.

If you want to store modification times of each file, I see two
options. One, you can commit each file as a separate revision, then
set the svn:date property of the just-committed revision to match
what the mtime of the file was. Repeat for all files.

Or two, you can attach a new property (e.g. x-mtime) to each time.
Set that property to the actual modification time of the file.
Perhaps invent a script which handles the commit, by attaching the
property and then calling svn ci. Invent another script to replace
svn checkout, which checks out, and then also sets the actual mtimes
of the files as per the contents of the new property.
