It's rare but sometimes a computer's clock keeps time so badly that NTPD
can't correct the clock.  If your clock gains or loses more than 43
seconds per day, get it fixed!  It's more than NTPD can handle.

BTW,  please use your "Return" key from time to time.  The first line of
your message is about three screens wide!  I just "rewrapped' the text.
