The CTEST_CHECKOUT_COMMAND should only be used for checkout. It should not
be used for update.

This comes from the ctest_update command, and it intentionally uses the
nightly date stamp to guarantee a consistent snapshot across clients.
Otherwise, you could get different source trees on different machines
depending on the timing of running the ctest_update command.
