I see this is a problem, but how many companies really need this? In my limited experience I have only seen clock sync issues at scale and simple NTP/Chrony setup solves majority of the problems, unless you're in HFT domain where PTP is needed. Nowadays, many of those atscale systems are getting SaaSified where the companies using them dont have to directly deal with such issues. What am I missing here? Is there really a big market for this?
