After the last update last monday my 8.1 HP microserver 40L has an extreme lag in time. If updated with ntupdate -u 0.smeserver.pool.ntp org it shows an offset of about 4.5 sec, if this command is repeated 40 seconds later it is 0.8 seconds and after 1-2 minutes it again raises up to 1 - 2 seconds increasing constantly. The server time is increasingly walking behind internet time.
Is this a hardware related problem or is there something wrong in another place?
It is standard hardware and was working 7/24 for about 1 year now.
