      Even Dimension 4 doesn't necessarily help. I was syncing every 2 minutes
      with Dimension 4 as well. I was using a source at Cornell and it was
      pointed out to me that I was off by a whole 30 seconds! As soon as I
      changed the source, everything was OK. Now I check every once in a while
      with WWV. I can't answer your question about improving the local
      accuracy, however. I think it is a rare PC that keeps good time locally.
