You can specify an NTP server in the Packstack answer file or as a CLI option and then Packstack will configure your nodes to use that NTP server. If you don't specify an NTP server then Packstack doesn't handle NTP so you will have to do it yourself. Either way, make sure that all nodes always have the correct time.

I m concerned about the manual steps involved and losing on my n/w connections in case i do anything wrong. Is there any reference on how to do this, i couldn't find anything specific on the quickstart page.
