<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Hello Guys,<BR>
<BR>
I hope you’re all well. I’ve been trying to resolve the clock drift issues again today and I’m struggling.<BR>
<BR>
I cannot use the ‘nomfgpt’ work around as we rely on the watchdog and doing so breaks it.<BR>
<BR>
I have installed </SPAN></FONT><FONT SIZE="2"><FONT FACE="Arial"><SPAN STYLE='font-size:10pt'>adjtimex and ntp:<BR>
<BR>
apt-get install adjtimex<BR>
apt-get install ntp<BR>
</SPAN></FONT></FONT><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'><BR>
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.<BR>
<BR>
Can anyone offer any other advice? I could always schedule a cron task to correct the clock but that seems so hacky.<BR>
<BR>
Thanks,<BR>
<BR>
Robert<BR>
