ntpd cannot fix that. chrony could, just. But it indicates some severe
problem. Is this a virtual server running on some other hardware?
Nothing can help then, except getting the server to get its time from
the underlying system, not its own clock. 

You could install adjtimex and use it to set the tick to cancel out most
of that , but I suspect it is not consistant either.

Nothing ntpd can do, sorry. The rate is far too far off. fix that
problem first. ( and if this is a virtual server, stop looking to ntp
for a fix)
