Can't adjust timezone in WHM

[@home]

I encounter a strange problem with 3 Cpanel VPS machines.
I try to adjust the server time in WHM because it is one hour behind (GMT-1) but I can't adjust it, it stays on GMT-1 whatever I select or Sync.

However Centos/cloudlinux 7 has the correct time.

I tried :
rm -f /etc/localtime
ln -s /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime

# /usr/sbin/ntpdate ntp.ucsd.edu ntp1.cs.wisc.edu
31 Mar 17:14:53 ntpdate[608397]: adjust time server 132.239.1.6 offset -0.000920 sec

The time is correct in SSH
# date
Thu Mar 31 17:14:56 CEST 2016

But in WHM it stays on GMT-1
Thu Mar 31 16:14:56 GMT-1 2016

It is a KVM VPS on Cloudlinux 7 WHM 54.0 build 21

Any ideas what could be the cause of this?

Hello ,

Have your tried to update server time though WHM >> Server Configuration >> Server Time ?

Off course I tried that, that is the whole problem. Whatever I select in WHM >> Server Configuration >> Server Time or Sync the time stays on GMT-1. If I choose Europe/Amsterdam or Australia/Sydney the timezone keeps the same GMT-1.
