title: S3 bucket script to add timestamp in filename on upload
body: <p>I'm looking for a way to add a timestamp in every file that is uploaded to an S3 bucket, Amazon-side. There is, of course, an option to do this client-side before the upload, but I don't think this is as nice and clean as it would be to have some script to run in the bucket itself everytime a new file is uploaded. I didn't find anything in the docs, though.</p>
