Hello All,

  I'm busy with the PCF8583 , and found something out that I don't like ...
 When running on a supply-voltage of 5 Volts, the clock run's OK, but when
the voltage drops to 2.5 to 2.1 volts (two backup accu's thru a BAT85
diode) the clock seems to go fast.

Does anyone have any experience with these Real-time clocks, and how to get
then stable ?  I would appriciate any pointers.

Regards,
  Rudy Wieser
