My VM on ESXi have all different dates. Here is how toset them the same.
First, you’ll need to install NTP. For Debian or Ubuntu, that would be this command:
# sudo apt-get install ntp
For Redhat or CentOS, you’ll need to use this one:
# yum install ntp
Then you’ll want to edit the /etc/ntp.conf file, which is quite possibly already filled out for you.
# nano /etc/ntp.conf
You can get a list of server addresses at www.pool.ntp.org. Here are the North America ones:
server 0.north-america.pool.ntp.org server 1.north-america.pool.ntp.org server 2.north-america.pool.ntp.org server 3.north-america.pool.ntp.org
Set it to run at boot
# chkconfig --list ntpd 0:off 1:off 2:off 3:off 4:off 5:off 6:off
For Redhat and CentOS 6
chkconfig ntpd on
# ntpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
For Redhat 7 and CentOS 7
# systemctl enable ntpd.service
CentOS 6 restart or start the NTPD service:
# /etc/init.d/ntpd restart
CentOS 7 Restart
# /bin/systemctl start ntpd.service
If you want to update the time right now, you can stop the NTP service and then run the following command, swapping out your preferred server for pool.ntp.org.
