Isn't there a 
UTC time associated with each file?
For instance, In PHP, you can do this: 
<?php
// outputs e.g.  somefile.txt was last changed: December 29 2002 22:16:23.
$filename = 'somefile.txt';
if (file_exists($filename)) {
    echo "$filename was last changed: " . date("F d Y H:i:s.", filectime($filename));
}
?> 
I'd rather see the number of restore points shown increased. Currently you only show 8 and it can easily be increased to 20 or so.
