If the system lacks an RTC, the time will typically start from the
epoch, and may get set to the "correct" time later (if at all).
In this circumstance, the timestamps in the cache tarball will always be
in the future. gnutar complains bitterly about this.

To work around this, use `tar -m` to strip mtimes during extract.
