The function was made, and an attempt to parse was complete, but never finished. It would be nice if implemented into library.

I used the code below for feather MO as interim

void updateRTC() { //Sets Internal M0 RTC from Structured ASCII msg from GSM Module char buffer[23]; fona.getTime(buffer, 23); rtc.setYear( ((buffer[1] - 48) 10) + (buffer[2] - 48) ); rtc.setMonth( ((buffer[4] - 48) 10) + (buffer[5] - 48) ); rtc.setDay( ((buffer[7] - 48) 10) + (buffer[8] - 48) ); rtc.setHours( ((buffer[10] - 48) 10) + (buffer[11] - 48) ); rtc.setMinutes( ((buffer[13] - 48) 10) + (buffer[14] - 48) ); rtc.setSeconds( ((buffer[16] - 48) 10) + (buffer[17] - 48) ); }

Check https://github.com/botletics/SIM7000-LTE-Shield it might have better RTC support.

https://github.com/adafruit/Adafruit_FONA/pull/76 from 2016 implements it, and it works perfectly for me on the FONA 3G. All it needs is to be merged in.
