It looks like the source for their FBOSS agent that runs on switches will enable PTP in two kinds of supported switches:
https://github.com/facebook/fboss/blob/master/fboss/agent/hw...
They have O(thousands) of switches (source: https://engineering.fb.com/2016/10/18/data-center-engineerin...) so IIRC they get the per-switch cost down by doing a custom design to reduce BOM. I believe the specs and designs are available under the Open Compute project here (search for "Facebook"): https://www.opencompute.org/wiki/Networking/SpecsAndDesigns

Just made reminded me that Facebook made this flicks library that can correctly map chrono duration typed to video playback rates...many rates do not map correctly to milliseconds.

What are some alternatives?
