Carry over not increment of current time date in example

[BallscrewBob]

Using the example https://create.arduino.cc/editor/ballscrewbob/4aa164b5-3012-4361-a7ff-d6a48eadea90/preview

The time carries over but does not INCREMENT the date and reset the clock to zero.

Had the same problem. I'm working on a MKR1400 which tends to hang after approx 24 hr (known issue with gsmclient), By monitoring the system overnight, I noticed the same problem. It corrected itself a 25:59 hr -> 02:00. If not solved: is there a work-around? Since I drop the collected data in mysql, the data with weird hours gets rejected and is lost. I can not afford to loose two hours of data every day. thx ahead ! Kris

Hello @Wijnbouwer and @BallscrewBob

I found the same issue and it seems that this hasn't been solved yet (please correct me if I am wrong!). I noticed that also the month and day, and year are not being updated after midnight until 25:59 hr -> 02:00.

I have this workaround solution that worked OK for me, but I am sure that the best way would be to solve the issue at a library level. I am quite new to Arduino (and programming, in general) so this probably not a really "clean" fix. The method for determining whether there is a leap year or not was proposed by the user econjack here https://forum.arduino.cc/index.php?topic=226313.0

#include <RTCZero.h> RTCZero rtc;

/* Change these values to set the current initial time */ const byte seconds = 50; const byte minutes = 59; const byte hours = 23;

/* Change these values to set the current initial date */ const byte day = 31; const byte month = 12; const byte year = 20;

void setup() { Serial.begin(9600); // establish communication parameters with serial port rtc.begin();

// Set the time rtc.setHours(hours); rtc.setMinutes(minutes); rtc.setSeconds(seconds);

// Set the date rtc.setDay(day); rtc.setMonth(month); rtc.setYear(year); }

void loop() { // put your main code here, to run repeatedly: int hour = (rtc.getHours() ); int mins = (rtc.getMinutes()); int sec = (rtc.getSeconds()); int day = (rtc.getDay()); int month = (rtc.getMonth()); int year = (rtc.getYear()); int daysInFebruary = 28 + leapyear(year); if (hour >= 24) {

//Workaround for RTC Zero library ver 1.6.0 bug #39
hour = (hour - 24);
day = (day + 1);

//Move from one month to another or change year

  if (month == 1||month == 3||month == 5||month == 7||month == 8||month == 10){
    //If the month has 31 days, change month when the day is already 31 (except for new year)
    if (day > 31) {
      day = 1;
      month = month + 1;
    }
  }
  else if  (month ==4||month ==6||month ==9||month ==11){
    //If the month has 30 days, change month when the day is already 30
    if (day > 30) {
      day = 1;
      month = month + 1;
    }
  }
  else if (month==2){
    //Move from February to March
    if (day > daysInFebruary) {
      day = 1;
      month = month + 1;
    }
  }
  else if (month==12){
    //Move from December to January of the next year
    if (day > 31) {
      day = 1;
      month = 1;
      year = year + 1;
    }
  }

} String timestamp = (use2digits(day) + "/" + use2digits(month) + "/" + String(year) + " " + use2digits(hour) + ":" + use2digits(mins) + ":" + use2digits(sec));

Serial.print(timestamp + "\n"); delay(1000); }

String use2digits(int number) { if (number < 10) { return "0" + String(number); // print a 0 before if the number is < than 10 } return String(number);
