Prob, energy consumption. The clcok is always on, thats the reason the freq is low as possible for cristals. Energy consumption is related to freq.

I used the next instructions:

  RTC.stop();
  RTC.set(DS1307_SEC,0);
  RTC.set(DS1307_MIN,03);
  RTC.set(DS1307_HR,21);
  RTC.set(DS1307_DOW,7);
  RTC.set(DS1307_DATE,1);
  RTC.set(DS1307_MTH,5);
  RTC.set(DS1307_YR,10);
  RTC.start();

it works fine   ;D , tried again today to be sure..

----------->  BUT if I change :

  RTC.stop();
  RTC.set(DS1307_SEC,0);
  RTC.set(DS1307_MIN,03);
  RTC.set(DS1307_HR,21);
  RTC.set(DS1307_DOW,7);
  RTC.set(DS1307_DATE,1);
  RTC.set(DS1307_MTH,5);
  RTC.set(DS1307_YR,13);   //<--------------- 13 !!
  RTC.start();

I see on the display the year 2000 !!! not 2013... >smiley-sad

Perhaps this sort of high level instructions does not work all the way ?

I tried to set the year of DS1307 with #include <DS1307.h>
till 2012 its OK
but e.g.

RTC.set(DS1307_YR,13);
or  RTC.set(DS1307_YR,98);
 dont work.
or date 31

what is the problem ?
