darcs points-in-time

Say I have a darcs URL and I "get" from it on July 1st at 8am. In the future (say, August 1st), on some other machine, I want to run a command that will produce the same files from the July 1st "get", with none of the changes that might have happened after that.

Is there some piece of metadata I can collect on July 1st so I can do what I want on August 1st? If so, how can I collect it and how do I use it?
