Re: [chrony-users] Chrony not taking SOCKET data from Application

[sarveshwar k <sarveshwar.kt@xxxxxxxxx>]

Hi Miroslav Lichvar,

Can you please provide below information:

Is it not possible to achieve synchronization accuracy less than 100ns with chrony (with GPS and 1PPS).

Can we configure chrony behaving as a measurement tool (not to make any corrections)?

Thanks & Regards

It will be in the next release. Backport the commit dec07aa844f8 from
the chrony repository to 3.5 shouldn't be too difficult. It's not
actually a bug, but rather a data-minimization feature which is not
necessary for reference clocks.
