/*********************************************************************************************\
DS3231 - its a accurate RTC that used in the SONOFF for get time when you not have internet connection
This is minimal library that use only for read/write time !
We store UTC time in the DS3231 , so we can use the standart functions.
HOWTO Use : first time, you must to have internet connection (use your mobile phone or try in other location).
once you have ntp connection , the DS3231 internal clock will be updated automatically.
you can now power off the device, from now and on the time is stored in the module and will
be restored when the is no connection to NTP.
