 The time-based lease scheme depends on the RTC clock. If the clock is
 significantly off, the XO will either refuse to run, or run with a 'never
 expiring' lease.

 So as part of
 http://wiki.laptop.org/go/XS_Blueprints:Lease_and_update_server we want to

  - Extend the 'OATS port 191' protocol to include a 'time' command.

    - Server implementation at
      http://dev.laptop.org/git/users/martin/xs-
 activation.git/commit/?id=c4e520820aa2788f8ce009a0d866613f4286a975

    - Client -- olpcrd -- implementation at
      http://dev.laptop.org/git/users/martin/olpcrd-
 rough.git/commit/?id=54500f5bb9925a8bb2bcff94f28bfa1f87e1e6e4

 The client implementation requires that we include hwclock and date
 binaries. We can either recompile busybox adding the hwclock/date
 functionality, or include the desired binaries.

 The git repo above contains binaries that work correctly on the XO in the
 initrd environment.
