NaiveTime can't be used on ATmega boards #7

When running get_time() on an Arduino Nano all methods of the NaiveTime object (hour(), minute(), second()) return 1.

Calling .get_hours(), get_minutes() and get_seconds() returns the correct values.

Interesting. Is the date and time set in the device correct? Can you set a time and/or date/time with set_time() / set_datetime()? How about get_datetime()?

I would suggest experimenting a bit with NaiveTime / NaiveDate and the related methods to see if you can find a cause.

When using NaiveDateTime, it bring many big data table related to date and time to the code!! The weird thing that happen is even the total .data, .bss surpassed the arduino nano capacity the code was flashed with no error I checked it with avr-size -A --mcu=atmega328p ...
