We need to use 1pps (gpio source) for timestamp in application.
I thought that ntp should be used with the linux pps for this purpose. But the system is standalone without any other servers connected. So the question is:
Is it possible to do it with ntp without other servers? How ntp.conf should be configured?
Does ntp use with pps means that system clock is synced with pps?
If ntp is not the way, is there other method to achieve sync of system clock with pps?
