I'm using this script:

#!/bin/sh
git log --name-only --format=format:%n%ct -- "$@" |
perl -e 'my $do_date = 0; chomp(my $cdup = `git rev-parse --show-cdup`);
    while (<>) {
	chomp;
	if ($do_date) {
	    next if ($_ eq "");
	    die "Unexpected $_\n" unless /^[0-9]+$/;
	    $d = $_;
	    $do_date = 0;
	} elsif ($_ eq "") {
	    $do_date = 1;
	} elsif (!defined($seen{$_})) {
	    $seen{$_} = 1;
 	    utime $d, $d, "$cdup$_";
 	}
    }'

Andreas.
