RTC DS3231 set time but serial monitor will not accept correct time, serial monitor shows wrong time

[catphomet]

Hello there. So if I set real time it doesn't show correct time in serial monitor.
1 sec lasts like 7mins. Checked all pins, sda,scl,vcc and ground. Later I figured out that I
accidentally connected DS3231 on 12V instead of 5V

Here is code

#include <DS3231.h>

// Init the DS3231 using the hardware interface
DS3231 rtc(A4, A5);

void setup()
{
// Setup Serial connection
Serial.begin(115200);

// Initialize the rtc object
rtc.begin();

// Write your current time and date to this following lines
rtc.setDOW(MONDAY); // Set Day-of-Week to Monday
rtc.setTime(13, 44, 0); // Set the time to 12:00:00 (24hr format)
rtc.setDate(29, 12, 2021); // Set the date to January 1st, 2014
}

void loop()
{
// Send Day-of-Week
Serial.print(rtc.getDOWStr());
Serial.print(" ");

// Send date
Serial.print(rtc.getDateStr());
Serial.print(" -- ");

// Send time
Serial.println(rtc.getTimeStr());

// Wait one second before repeating
delay (1000);
}

Hi @catphomet

I hate to be the bearer of bad news, but you blew the clock.

That photo is taken from the data sheet. The sensor has a max voltage of 6V on any pin. 12V is double.

Did you try replacing it? Did it work before? etc. etc.
