I came across an interested project to try with the Uno R4, but no successful compiling with the delivered libraries. The project works with the Arduino Uno Standard with no error.After some research I found the hint to use the compiler option '--std=c++11!Now I find no place or file to enter or try those options with the Elektor Uno R4 Hardware in the Arduino 1.8.10 or other.Please indicate how to enter the options in this case or another workaround. The compiler options a very useful also for other cases.Thanks in advance. AS

Because the NMEA messages are likely from a buffered queue. No guarantee the queue is timed consistent from unit to unit. That's exactly why the 1PPS signal comes out of the GPS module, it is synchronized much tighter to GPS time, and could have jitter in the low nanoseconds. Sync your clock to the NMEA message, but adjust the timer according to the 1PPS signal. There is tons more published regarding this task, search the "time nuts" mailing list archive.
