PTP Time sync

Has anyone tried to sync the time on two TK1s or a TK1/TX1 using PTP? Is that possible?

I’m not sure what you’re looking for, but Linux can work as a network time protocol (NTP) server and/or client. I’ve never set one up as a server, but I see no reason why a Jetson could not do this (L4T already has setup for NTP client).
