Edit your /etc/ntp.conf and file the lines starting with "server. Edit the hostnames to contain your preferred ntp-servers:

server 0.debian.pool.ntp.org iburst dynamic
server 1.debian.pool.ntp.org iburst dynamic
server 2.debian.pool.ntp.org iburst dynamic
server 3.debian.pool.ntp.org iburst dynamic

Then restart ntp-service

/etc/init.d/ntp restart

Check the results after a few minutes:

ntpq -p

why do you not have VMware Tools installed and Sync-ing time with the host?

Hanccocka,  good question, I did not install the software and the person who did is gone and left very little documentation.  I would not know how to install the VMware Tools on linux if my life depended on it.

It's beneficial to have VMware Tools installed not just for Time Sync.

How do I edit the  /etc/ntp.conf file and how to I install VMWare tools on the Linux server?

It's important to note that if your Debian VM was configured to synch time with NTP, as opposed to using VMware Tools, then there is a possibility that any other VMs are also set to sync to that same time source, and there could be a valid reason for doing so (Corporate standards, etc.)

You want to make sure that you confirm what the standard time sync practice is on all of your virtual and physical machines before you go ahead with configuring VMware Tools to sync the time with the host.

When your ntp is running and reaching the ntp-servers, you'll see a listing like this with ntpq -p.
The reach, delay, offset and jitter values are mostly non-zeros when it works fine.
