Richard's change works just as well as adding DATE to BB_HASH_WHITELIST.

In my minimal test, there are three packages being rebuilt: dbus-1,
base-files and shadow-sysroot.  It's still not clear to me why this
happened.  I've put the tmp/stamps trees at http://www.mlbassoc.com/misc/poky_stamps.tgz
This has two directories in it
   p60_test_pass1 - the original tree, build without any sstate
   p60_test_pass2 - the dependent tree, build using p60_test_pass1 as sstate
Perhaps someone can give me a clue why these three packages were
rebuilt.  Note: there were no changes to the source repository
between the two builds and I always build with BB_NO_NETWORK="1"

Thanks
