Accurate time without a network connection?

Looking for options to keep system time moderately accurate at a site
without network access. So the normal application of ntpd over IP is
not viable. Dialup modem not allowed either.
Definition of "moderately accurate": doesn't have to be any better than
I can set my watch, travel to the site, and set the system time. It just
has to eliminate "travel to the site."
A GPS is one possible solution using the appropriate ntpd driver. Am not
sure I can place the GPS antenna in a suitable location.
A WWV receiver would be another viable option but I am not having any
great success in finding a prebuilt receiver with decoder suitable for
direct connection to serial port and ntpd.
