In addition to what Anthony mentioned. If your want to provide ntp service
to others(sounds like that is what you wanna do), you need "ntp master"
instead of "ntp server"
 From Cisco.com <http://Cisco.com> :
 Configuring the System as an Authoritative NTP Server

Use the following command in global configuration mode if you want the
system to be an authoritative NTP server, even if the system is not
synchronized to an outside time source:
  Command
 Purpose

Router(config)# *ntp master *[*stratum*]

Makes the system an authoritative NTP server.
