I don't know about an internal board but here at rsiatl, we have a 
Heathkit "Most Accurate Clock" that receives WWV and decodes the 100 hz
data carrier and makes it available on an RS-232 port.  We have a small
Perl script that reads this data from the port and sets the system
clock.  Thus the timestamp on this article is WWV-accurate to within
a second :-)  Our script reports how much correction must be made
each time it runs.  A second a day is normal.
