8am-12:15pm in UTC which corresponds to 1:45pm-6pm in NPT The first thing to do is to install the NTP server INIT An NTP network usually gets its time from an authoritative time source, such as a radio clock or an atomic clock that is attached to a time server Grab the package by running: Ubuntu operating systems / Debian: sudo aptitude update sudo aptitude install ntp CentOS: sudo yum install ntp Ater you install NTP , you can ensure the service runs at boot time by running the following command: sudo /sbin/chkconfig ntpd on Fedora / RHEL: AUTH Now we instruct our Cisco router to obtain its updates from the public NTP server 00 msec The Cisco implementation of NTP does not support stratum 1 service; that is, you cannot connect to a radio or atomic clock (for some specific platforms, however, you can connect to a GPS time-source device) The ES- 976/NTP -C is an NTP Time Display featuring 7" high red LED displays NTP is a TCP/IP protocol for synchronizing time over a network NTP
