I have a soucre control stream for a current prod release called 'prod'.  The developer have been making some changes for iteration 2 and I have created a source control stream for them called 'rel2'.

I'm getting ready to deliver 'rel2' to the customer, but I only want to deliver the changed files.   If a file has not changed from release 'prod' we don't want to send it to them.

What is the easiest way to extract them?  I was dismayed to discover that when I load a repository workspace to my local drive, every file is given a new datestamp.   I was hoping to just get the 'newer' dated files but it looks like that won't work.

Ideas?
