RTC not functioning correctly

Hi Community,

I have 2 Lora loggers (with the exact same code) running and capturing the transmission from Lora sensor units.

Every transmission is time stamped by the logger. 

If you look at the image attached, you'll see the logs of the 2 loggers. 

If you look at the bottom one before midnight the time stamp is 2018-10-03 23:59:39 and then after midnight 2018-10-04 00:01:38

But if you look at the top one before midnight the time stamp is 2018-10-03 23:59:53 and then after midnight 2018-10-03 24:01:53

The issue is that the date of the top logger doesn't go from the 03 to 04, instead the time just increase pass 24 hours. This appears to be a very random issue, as this doesn't happen every day.

I don't know how to resolve this issue, because both loggers are running the same code.

Rolling over 24 hours is an indication that the RTC is set in 12-hour mode and time was set on it beyond 12:59:59.

Now how that might have happened, this question has to be asked the author of that firmware.
