A DCF77 receiver capable of working out of the box with FreeBSD costs
19,95 DM and is setup in a minute. You get a _very_ accurate clock
cheap and with almost zero work.
The ISDN time in Germany is sent as Hour:Minute so the accuracy is bad
as even the Telekom does not give any guarantee or even a specification
about its acurrateness. More work has to be done in that something like
xntpd has to be written for setting the time via ISDN.
Baseline: in case you are at least a bit serious about your clock's time,
get yourself a cheap DCF77 clock and forget about setting time
from ISDN.
Hint: have a look at this FAQ which occurs every two weeks in the german
ISDN newsgroups and is answered there much more detailed.

Have a look at the description in the handbook. Its explained in detail there.
