You could do a network share between your two machines - 100' isn't
far at all to drop an ethernet cable into a slot you could cut in your
turf with a flat shovel. The either machine could do a synch; if it
was the one in your house, then the remote one could synch to it.
Yes, some tinkering will be necessary. If you either 1) fix the reason
your system crashes &/or 2) put your overall Linux on a bootable CD,
then losing your config won't be an issue. And it's sure cheap.
A Trimble Acutime 2000 system would be able to give you, I think, UTC
to 10ms. More fiddling & cost, but you'd be independent from dialup.
(Here's a Trimble Acutime kit that went on eBay just over a week ago:)
