Converting GPS seconds to Gregorian date/time on the Arduino will be an arduous task. You take GPS seconds and add it to the GPS starring epoch to get a Julian date. Then add in the number of leap seconds as a fraction of a day to get UTC and possibly add in a time zone offset for local time. Don't forget to do daylight savings time conversion... Then convert the result to Gregorian date/time for display.
The problem is the Arduino floating point library is single precision only and does not have the resolution needed to handle the numbers involved. Doing it with integer arithmetic (long longs) opens up a whole new can of worms. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
