With these NMEA devices the resolution comes from the chipset. As below, the time is 09h37m52s, the milliseconds value is always returned as zero. Not all NMEA sentences are returned by every device, mine doesn’t return the timestamps.
They are easy to read – just open the COM port and read the text.

time_t timeGetTime(); That has millisecond resolution - if running with mm timer set to 1 ms. Then there is the precision (100ns) timer with motherboard dependent actual resolution. I use timeGetTime() most of the time. One must handle it's roll over, of course. With time64_to work with on 64 bit builds that's not much of a problem. It is always a relative time to when the computer boots. But that offset can be backed out if critical. On 20220511 00:10:26, Simon Brown wrote:
