Welcome to the `pcfclock' driver and the `pcfdate' utility!

The `pcfclock' driver for GNU/Linux supports the parallel port radio
clock sold by Conrad Electronic under order number 967602.  The radio
clock, which is put between a parallel port and your printer, receives
the legal German time, i.e. CET or CEST, from the DCF77 transmitter
and uses it to set its internal quartz clock.  The DCF77 transmitter
is located near to Frankfurt/Main and covers a radius of more than
1500 kilometers.

The `pcfdate' utility gets and displays the date and time from a
`pcfclock' device and optionally sets the system time.

Files you might look into:

`COPYING' -     copying conditions
`INSTALL' -     compilation and installation rules
`NEWS' -        major changes in the current version
`THANKS' -      list of contributors

Starting with version 4.0.98g the Network Time Protocol distribution
supports the `pcfclock' driver.  Visit http:/www.ntp.org/ for more
information about the Network Time Protocol.  Unfortunately, the
Conrad parallel port is very imprecise which causes NTP to regularly
lose its synchronisation.  It might be possible to add a filter that
corrects the time signal to the NTP reference clock driver but I do
not have the time to write such a filter.
