If "ntpd" makes small adjustments (which it tries), then
there will be no problem with ZODB.

   All our Zope hosts run nntpd and we never have had problems.

However, (a long time ago), we had an NTPD failure which
resulted in setting the date to the year 2036.
This would seriously confuse the ZODB (when later the date is
reset again).
