Off by several hours. I suspect the machine that signed
the zone has the timezone incorrectly set with the "correct"
local time being displayed. The fix is to correctly set
the time zone on the machine then re-set the clock so that
it displays the correct local time. This will result the
machines concept of UTC being correct. dnssec-signzone
already signs the zone with the starting time set to
1 hour earlier than the real signing time.

i.e. 14:21:26 when it was 15:21:26

Below are received lines from the original email showing
the time the first message was processed. mx.isc.org is
syncronised using NTP and I suspect victor.provo.novell.com
is as well as it's timestamp is 1 second earlier.

DNSSEC doesn't require NTP's precision. It just requires
the clock to be reasonably accurate +/- 15 minutes would
be fine.
