getEpoch() returns wrong epoch on Arduino NANO

[nicknugget]

When calling getEpoch it returns an Epoch that is 36 years (!) in the future, despite date and time are set and shown correctly.

Simple test code:

#include <Arduino.h>
#include <I2C_RTC.h>

static PCF8563 RTC;

void setup(void) {
  Serial.begin(9600);
  while (!Serial)
    ;

  // Start RTC and check status
  RTC.begin();
  if (!RTC.isRunning()) {
    RTC.setDateTime(__DATE__, __TIME__);
    RTC.updateWeek();    
  }
}

void loop(void) {
  if (RTC.isRunning()) {
    Serial.print("Time: ");
    Serial.print(RTC.getHours());
    Serial.print(":");
    Serial.print(RTC.getMinutes());
    Serial.println();
    Serial.print("Date: ");
    Serial.print(RTC.getDay());
    Serial.print("-");
    Serial.print(RTC.getMonth());
    Serial.print("-");
    Serial.print(RTC.getYear());
    Serial.println();
    Serial.print("Epoch: ");
    Serial.print(RTC.getEpoch());
    Serial.println();
    delay(1000);
  }
}

Output:

Time: 9:35
Date: 31-8-2023
Epoch: 2832768244

Which nano board exactly?

[DavidMS51]

I am finding this problem with a 'generic' v3 nano clone

[cvmanjoo]

Arduino nano uses Atmega328p itself, right?

[DavidMS51]

yes that is correct

Fixed in v1.9.0
