  I2C1.setup({scl:SCL,sda:SDA, bitrate:100000});
  
  var rtc = require("DS3231").connect(I2C1, { DST : true });
  rtc.setDate(Date().getDate(),Date().getMonth(),Date().getFullYear());
  rtc.setTime(Date().getHours(),Date().getMinutes(), Date().getSeconds());
  
  setInterval(function() {
  console.log(rtc.readDateTime());
  }, 1000);
