The best way is to synchronize the VM _hosts_ using NTP or PTP or

I have connected 2 Virtual Machines to the same network using NAT network
configuration in Oracle VM Virtualbox Manager.
They have been successfully connected since I am able to ping between
the two systems successfully.

Are you sure you do not have ntpd, chronyd, or systemd-timesyncd running?
The "clock jumped forward" message typically indicates that another
software component is adjusting the clock
A lot of VM software includes a guest component which re-synchronizes the guest
clock to the host automatically. This allows you to "suspend" the host (i.e.
shut the laptop lid) and then bring it back and have the time in the guests be
correct (among other uses).

As you mentioned i stopped systemd-timesyncd,and now the statement clock
jumped forward isnt there,but the clock isnt still synchronized.
*Master clock Machine*
command 1: sudo ptp4l -i enp0s3 -S -m -2 //S indicates software stamping
and -2 indicates that it's an ethernet connection to the slave
How do I disable this guest clock?Is there a name for it?Any leads?
