ignore subdirectories timestamps when syncing from shell
<p>i want to write a shell command to sync current directory to backup directory with some requirments. the  command i'm using is: </p>

<pre><code>   rsync -ptvHS --progress --delete-after --exclude /backup  $pwd ~/backup
</code></pre>

<p>i want the directory timestamps to be ignored, eventhough i use  -t to preserve the file timestamps.
Any idea?
thank you in advance</p>
