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.
