I want to get the exact time from the GPS without using the system time. It is important for me to get the exact time to 1 millisecond. But the system time in android on different smartphones, shows different times at 1-5 seconds sometimes more. I hope that the time from the GPS on all devices located nearby in one place will be the same from 1 millisecond. As an option, is it possible to force Android to correct the internal clock according to the GPS all the time? Because the time from cellular operators is less accurate. I need to synchronize clocks on different devices with maximum accuracy.
