my ntp config
This is what I use at home. For the data center I would always recommend having your own internal time source and then synching THAT with a tier 2 server.
Basically comment out ntp server info that may already be in /etc/ntp.conf
and replace with the following by adding to the end of the file:
ntp servers
restrict time.nist.gov mask 255.255.255.255 nomodify notrap noquery
restrict time.nist-a.gov mask 255.255.255.255 nomodify notrap noquery
server time.nist.gov
server time-a.nist.gov
Don’t forget to recycle the ntpd daemon ( on Red Hat systems, /sbin/service ntpd restart
).
