Linux NTP/PTP timestamps

Hello,

I have a 1095 PXIe Chassis and 7972R FlexRios. I am trying to get a RHEL computer to decode a timestamp. I know windows does this with the 6683H module, but is that is unsupported in Linux. Are there any modules that can decode timestamps for RHEL? Is there a route to get NTP/PTP timestamps from a server?

Thanks,
