How do I edit the time on an ESX server (vi3)

Hello all,

What is the command to edit\configure\change the time on an esx host.

Thanks,

You can check your ESX server hardware clocks by typing in:

Hwclock --show

You can modify the system time by typing

Date MMDDhhmmYYYY.ss

You can then sync the hardware clock with the system time by typing

Hwclock --systohc

You can change it with date -s but you may want to instead set it to sync with an external NTP source - http://kb.vmware.com/kb/1339. If you have version 2.5 of the VI client installed you can also set the NTP setup on the Configuration \ Time Configuration page.

you can also configure ntp

the file is in /etc/ntp.conf

configure step-tickers

the file is in /etc/ntp/step-tickers

and open firewall for ntpClient

esxcfg-firewall --enableService ntpClient

To all,

Much appreciated... we usually sync up to our time servers (our active directory). we open the ntp 123 port and have to edit step-tickers, and the ntp.conf file to do this. Net Eng forgot to open the ports so our VMs were all way off since the hosts were showing a date of sept of 07 and 2 hours off. I had to manually set the time until they opened the firewall ports for this.

Funny thing is... once i manually corrected the time, net eng got on and opened the ports... go figure.

Thanks again for all the responses guys.
