title: I can't get DS3231 RTC to work
body: <p>I have a DS3231 RTC module and I am trying to read time off of it using my Arduino UNO through I2C. I'm using the sample code provided with the library but it doesn't seem to work.</p>
  
  <p>The only thing I get out of the serial monitor is this:</p>
  
  <p><code>20165-85-165 25:165:165
  Temperature=254</code></p>
  
  <p>I was getting the same thing with another RTC module as well and my guess (which probably isn't true) is that they might have overflown though there doesn't seem to be a reset pin.</p>
  
  <pre><code>#include &lt;DS3231.h&gt;
  #include &lt;Wire.h&gt;
  
  DS3231 Clock;
  bool Century=false;
  bool h12;
  bool PM;
  byte ADay, AHour, AMinute, ASecond, ABits;
  bool ADy, A12h, Apm;
  
  byte year, month, date, DoW, hour, minute, second;
  
  void setup() {
      // Start the I2C interface
      Wire.begin();
    #define oneTime
    #ifdef oneTime
      Clock.setSecond(50);//Set the second 
      Clock.setMinute(59);//Set the minute 
      Clock.setHour(11);  //Set the hour 
      Clock.setDoW(5);    //Set the day of the week
      Clock.setDate(31);  //Set the date of the month
      Clock.setMonth(5);  //Set the month of the year
      Clock.setYear(13);  //Set the year (Last two digits of the year)
    #endif
          // Start the serial interface
      Serial.begin(115200);
  
  }
  void ReadDS3231()
  {
    int second,minute,hour,date,month,year,temperature; 
    second=Clock.getSecond();
    minute=Clock.getMinute();
    hour=Clock.getHour(h12, PM);
    date=Clock.getDate();
    month=Clock.getMonth(Century);
    year=Clock.getYear();
  
    temperature=Clock.getTemperature();
  
    Serial.print("20");
