Clock Features - What is new in version 5.9.
Revision 12.12.2005

The DCF77 mode is now showing DATE and MONTH and YEAR, if in 6 digit mode. If in 4 digit
mode the DATE and MONTH are shown, not the year. Every minute when the seconds go
from 50 to 55, the date is shown. If no valid DCF77 string has been received after a 23:59 to
00:00 change, the date will not been shown, until new valid string has been received.
In the two digits modes, no date will be shown no matter what, sorry. But DCF77 mode is still
useful /possible to set the clock.

Please note: Showing the date is only possible in Europe (1500 km around Frankfurt/Main). No WWVB
signal can be decoded at present.

Here is a small video that show the date - clock change.

We cannot guarantee DCF77 reception outside Germany.

If you use +/- 1 hour adjustment in DCF77 mode to compensate for your local time zone the
date shown around midnight will be wrong. The date readout was made for German users
only.

If you don’t want the date to be shown in DCF77 mode, please connect a short circuit in the
DCF/programming connector J1 from pin 2 and 4 - that is RB7 from PIC - to ground.
