Understandable.  The 12 hours behind could be caused by an incorrect
time zone somewhere - make sure m0n0 knows what zone you are in as well
as the syslog server...  Unless you're doing all logging in GMT or
something, at which point you should make sure all the devices know this
is the case too.  ;)

Is your hardware a PC, and does it ever get powered off?  It could be a
bad CMOS battery fouling things up.  Another thing to keep in mind is
that many implementations of NTP don't like to make gross adjustments to
time beyond a certain point.  I've seen systems that have been off by a
month and it won't set the time because of this.  Try to manually get it
within at least a few minutes by changing it in the CMOS if needed...

If this is the case, you shouldn't need a DNS server for it to work...

http://m0n0wall/system.php (the "General setup" item)
Found in the "DNS servers" section as "Allow DNS server list to be
overridden by DHCP/PPP on WAN".

If you manually set an address in the fields you don't need this
checkbox - you may not even need it if you leave them blank, but I'm not
sure and haven't tested that.
