I have 3 PCs (Ubuntu 18.04 + kernel 4-19 (custom)). I try to use scheduling with qdisc, which uses base-time for start schedule (UTC time) and as CLOCK = CLOCK_REALTIME/TAI or MONOTRONIC. All PCs are synchronized with ptpd2 , which shows offset on time between Master and Slaves, but PCs haves differences in time . How can i dynamicaly adjust clocks on PCs and in "real-time" adjust the CLOCK_REALTIME or TAI? Is it possible?
