According to Poul-Henning Kamp:

Depends. DCF77 Precision is not very good but it works. 

status=0003 clk_okay, last_clk_fault
device="RAW DCF77 CODE (Conrad DCF77 receiver module)",
timecode="-----------------D--S--4--2-p-2---2p-24----2-124--1--81--8p",

refclock_time="bb2ce473.00000000  Tue, Jul  6 1999 22:24:19.000 (+0200)",
refclock_status="DST; TIME CODE; (LEAP INDICATION; ANTENNA)",
refclock_format="RAW DCF77 Timecode",
refclock_states="*NOMINAL: 27d+09:50:08 (85.76%); NO RESPONSE: 2d+14:47:44 (8.18%); FAULT: 03:18:35 (0.43%); ILLEGAL DATE: 1d+19:05:32 (5.61%); ILLEGAL TIME: 00:01:31 (0.00%); running time: 31d+23:03:30"

Pierre who lives in Paris often get a better score (around 95% I think).
Advantage is that the DCF77 receiver is very cheap (200 FF -- 30 US$).
