Hello, I am playing with ds3231 and the library from Adafruit, in the examples for ds3231 shows days since 1/1/1970, if I go online and check the days from 1/1/1970 to now they are very different, almost 400 days difference. Is there a reason for this?
The seconds since 1/1/ 1970 is correct but calculation of the day isn't. Is there a reason for that?
What numbers are you getting? What numbers do you expect to get?
What Web site are you using?
Have you tried calculating the number of days yourself, using a calendar and a calculator? What number do you get?
