[time-nuts] Lady heather plus NTP server?

[ken johnson]

I currently have my router/firewall acting as both an NTP client, getting
it's time from the net, and an NTP server serving my home network. Now I
have my thunderbolt and Lady heather working nicely, I would like to have
that machine act as the ntp server for my network, but it appears ntp can't
understand tsip, and also with LH taking the com port, I can't see a way of
ntp getting the data anyway.

Is this possible to do, and if so,  can anyone give me some clues as to how?

Thanks, Ken.
