As Uwe said, you can't really do that in R. S-PLUS can do that because it stores each object as a separate file on disk, thus you can get time stamp from the file. In R everything is in the global environment that can be saved to a single workspace (.RData by default).

There have been some discussions quite a while ago on how time stamping objects in R can be done. You may want to search the archive. The mbvutils package has tools for organizing objects, but I don't know if it provides time stamps.
