Various revisions of encoded data slices stored in a distributed storage system can be time stamped to assist in retrieving desired data revisions. Each of the multiple revisions of the encoded data slices may have the same name, but different revision numbers. An encoded data slice, which is received at a distributed storage unit along with a write command, slice name, and the revision number, is time stamped. The timestamp and revision number are stored in conjunction with the data slice. A desired encoded data slice can be retrieved by sending a read command, slice name, and timeframe to the distributed storage unit. The appropriate encoded data slice can be retrieved by determining which revision number has a timestamp most closely matching the requested timeframe.
