What are satellite time, GPS time, and UTC time?

WebTo complicate matters, the resolution appears to be 7 ns when using modes 2 and 3. Duration of the clock_gettime () call is more like 1500 ns for modes 0 and 1. It doesn't make sense to me at all to claim 70 ns resolution on the time if it takes 20 times the resolution to get a value. Some modes of clock_gettime () are faster than others. WebA GPS receiver can shorten its startup time by comparing the current time, according to its RTC, with the time at which it last had a valid signal.
