[Days, Months, Years] Issue

Could change to fix: float time = atoi(_tokens[1]); -> float time = atof(_tokens[1]);

What error do you get? It is intentional. I don't support milliseconds (after optional dot), so I'm only getting an integer.

int time = atoi(time); is equivalent of: int time = (int)atof(time);

All values like hours, minutes and seconds are integer, not float.

atoi() The function first discards as many whitespace characters (as in isspace) as necessary until the first non-whitespace character is found. Then, starting from this character, takes an optional initial plus or minus sign followed by as many base-10 digits as possible, and interprets them as a numerical value.

The GNSS chip which support more than one category satellite, data looks like: $GNGGA,190012.000,xx16.88468,N,xxx27.75270,E,1,09,1.6,30.8,M,0.0,M,,43 $GNRMC,190012.000,A,xx16.88468,N,xxx27.75270,E,0.02,0.00,280620,,,A78

So, the "time" is float, if "atoi" will have error in output.

Btw, it is Arduino Nano w/ ATmega328P and NeoSWSerial.

I know it can be float, but this is not a bug. You don't need milliseconds to calculate seconds, minutes and hours.

Take a look:

No errors. I don't need floating point precision.

In the future I might consider adding a new millisecond variable (as int).

I know the results of atoi and atof both are correct time format in this case. However, only atof function works on my Nano board with Arduino IDE 1.8.13 with unknown reason...

Thanks for your feedback :)

Now I understand your problem, but without error message I can't help more now. If I have the opportunity I will check it.
