You can get ready-made receivers for the Rugby (UK) and DCF (Germany +
?europe?) time transmissions, of course this is only useful if you're
in range. Another (less accurate) alternative is to use RDS (radio
data system) in areas where this is transmitted on FM broadcasts.
GPS is probably the most universal, but the antenna needs a good view
of the sky, and is relatively expensive (compared to DCF etc., but
getting cheaper rapidly), and takes a relatively large amount of
power.
