But are you using a chronodot with the logger shield?

Yes, I do. The chronodot is mounted ( intagrated) on the Datalogger.

That won't work. The Chronodot and the DS1307 have the same I2C address, and therefore can't share the same bus. You will have to remove the DS1307 from the datalogger

The question was why the RTC cannot be synchronize?
// following line sets the RTC to the date & time this sketch was compiled
// uncomment it & upload to set the time, date and start run the RTC!
RTC.adjust(DateTime(__DATE__, __TIME__));
But i still see the serial monitor printing:
2165/165/165 165:165:85
since 1970 = 1396827985s = 16166d
now + 7d + 30s: 2014/4/13 23:46:55




and you guessed, that RTC was damaged.
So

It's possible that the RTC is damaged, then. All I can do at this point is to replace the datalogger. Please email support@adafruit.com with a link to this thread.

fix for the
2165/12/31 23:60:60 since midnight 1/1/1970 = 1890322364s = 21878d now +7d +30s: 2029/12/2 17:33:14
this just repeats on and on and on nothing changes

using the example for ds1307
replace all ref to ds1307 with ds3231
and remove the if statement and that fixes it woot
