How to enable PTP(Precision Time Protocol) support on Manjaro?

How to enable PTP(Precision Time Protocol) support on Manjaro? It seems that I can install linuxptp from AUR I am wondering if I need other tunings or configuration.

Unless you have some very specific requirements and you the admin of a large enterprise network you don’t need it.

Manjaro already use ntp to synchronize the clock. (systemd-timesyncd)
No need for ptp.
