A nice idea, but I would not - as the radio clocks I have seen can be out
by 500ms and are not that reliable. My GPS is far better. If I didn't
have GPS, or I wanted a backup though, I might bet one.
By the way, I don't see why Internet-connected PCs should be that far out,
as Microsoft now runs its own NTP server, and most recent versions of
Windows include at least an SNTP client. Should really be pre-configured.
