I totally agree with you that the mtime feature is needed in Subversion.
Hopefully the issue doesn't get sidetracked yet again. I've got my fingers
crossed that issue 1256 gets attention.

The hack we've implemented as a work-around is to set a file property called
mtime on each of the imported files. (At the time when you do an initial
import, you presumably have a copy of the original files with their
historical modification times, outside of subversion.) Then, after checkout,
run a script that 'touches' the local working copy to use 'mtime'. Now you
have a local working copy of files that are version-controlled and reside on
the local file system displaying timestamps that reflect their 'mtime'
property. You could combine this with a post_commit hook so that mtime (the
property) gets updated on any subsequent file modification.

pushd /home/user/work/project-working-directory
        for FILE in `find . -mindepth 1|grep -v '.svn'`
                echo Setting custom mtime on $FILE
                svn proplist "$FILE"|grep 'svn:mtime' >/dev/null
                if [ "$?" -eq 0 ]
                        MTIME=`svn propget svn:mtime "$FILE"`
                        touch -d "$MTIME" "$FILE"
popd >/dev/null
