Page 15: Time Management Overview
CHAPTER 1 Time Management Overview NTP Overview on page 3 Understanding NTP Time Servers on page 5 NTP Overview Network Time Protocol (NTP) is a widely used protocol used to synchronize the clocks of routers and other hardware devices on the Internet. Primary NTP servers are synchronized to a reference clock directly traceable to Coordinated Universal Time (UTC).
Page 16 Time Management Administration Guide for Routing Devices NTP Client—NTP clients are synchronized to a primary or secondary NTP server. Clients do not re-distribute this time data to other devices. NOTE: The NTP subnet includes a number of widely accessible public primary time servers that can be used as a network’s primary NTP server.
Page 17: Understanding Ntp Time Servers
Chapter 1: Time Management Overview NOTE: NTP is required for Common Criteria compliance. For more information on the Common Criteria certification, see Public Sector Certifications In Junos operating system (Junos OS) Release 11.2 or later, NTP supports IPv4 VPN routing and forwarding (VRF) requests.
Page 18 Time Management Administration Guide for Routing Devices NOTE: In NTP server mode, the Junos OS supports authentication as follows: If the NTP request from the client comes with an authentication key (such as a key ID and message digest sent with the packet), the request is processed and answered based on the authentication key match.

Page 23 Chapter 2: Configuring Time [edit system ntp] user@host# set server 0.north-america.pool.ntp.org (Optional) Set the local time zone to match the device’s location. Universal Coordinated Time (UTC) is the default. Many administrators prefer to keep all their devices configured to use the UTC time zone. This approach has the benefit of allowing you to easily compare the time stamps of logs and other events across a network of devices in many different time zones.

Page 29: Example: Configuring Ntp As A Single Time Source For Router And Switch Clock Synchronization

Time Management Administration Guide for Routing Devices of day and date is obtained when the router boots. The statement identifies the server NTP server used for periodic time synchronization. The statement authentication-key specifies that an HMAC-Message Digest 5 (MD5) scheme should be used to hash the key value for authentication, which prevents the router or switch from synchronizing with an attacker’s host posing as the time server.
