||The DCF77 radio controlled clocks receive the official
time of the Federal Republic of Germany from
Physikalisch-Technischen Bundesanstalt (PTB) in Braunschweig.
The radio synchronisation of the DCF77 transmitter in
Mainflingen (50 01 N, 9 00 0) reaches a long-term accuracy of
the PTB-calibration standard of 1 x 10 E-13 per
week or less than 1 second in 300,000 years. Due to its high
accuracy, only this |
time is accepted as legally binding in
the Federal Republic of Germany.
