Ouch... That's kind of expensive if you just want time. Why not get one of the 
kits
for the LF transmissions from Boulder, US in North America or Rugby, UK for 
western Europe.
(I think there is a German source also covering Europe)

These transmissions (Boulder and Rugby) are 60KHz AM at 1pps. The actual date
is encoded in the 1pps (differently for the two though)

My reciever for this cost me about $10. (It was my design, still a kit should 
cost less than
$30). The antenna is a ferrite rod, like the old AM radios used.
