Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have 3 servers and each one of them is showing different time. How do I correctly set the SAME time across all severs? I noticed that ntpd server is stopped. So I started it.

service ntpd start

Is it the correct way to sync time? (Indian Standard Time)

You are on the right track: edit your ntp.conf file to use the following servers (probably best for you):

   server 0.asia.pool.ntp.org
   server 1.asia.pool.ntp.org
   server 2.asia.pool.ntp.org
   server 3.asia.pool.ntp.org

Put the same servers in /etc/ntp/step-tickers and restart ntpd on all servers. That is all you need.

Use the same configuration files on all servers, of course

Perhaps make sure NTP clients are running periodically on all three servers and they are pointing to the same NTP server to sync time.

Might also want to stop ntpd once and run ntpdate against your chosen time server to make an initial correction, then start ntpd to have it do it's thing. –  Bart Silverstrim Jan 5 '10 at 15:11
