Hello Guys, I hope you're all well. I've been trying to resolve the clock drift issues again today and I'm struggling.
I cannot use the 'nomfgpt' work around as we rely on the watchdog and doing so breaks it. I have installed adjtimex and ntp: apt-get install adjtimex apt-get install ntp Which I thought may solve the issue as some others have suggested but even with this the clock still drifts wildly, and after just a couple of hours the clock is already several minutes out of sync. Can anyone offer any other advice? I could always schedule a cron task to correct the clock but that seems so hacky.
