The timestamp is only in the RVM log. It takes some work, but it is
possible to recover from this.

- Set the clock a day or so into the future (past the timestamp of the
  last modification).
- Use rvmutl 'recover' to commit any pending operations.
- Set the clock back to realtime.
- Use rvmutl 'init' to create a new empty log.

It would be nice to have some '-force' flag for rvmutl recover to commit
operations even with a clock-skew, but I'm not yet familiar enough with
the rvm internals.

I totally agree :)
