Webphc2sys: It is a utility program to synchronize the normal Linux system time to a PTP Hardware Clock - which itself is synchronized by the ptp4l program/application. For phc2sys, the terms ‘slave’ and ‘master’ are not about the PTP, but rather about two local clocks. Usually, the Linux system time is the slave, and the PHC is the master.
