Example: config>system>time# dst-zone pt
config>system>time>dst-zone# start second sunday april 
02:00
end first sunday october 02:00
config>system>time>dst-zone# offset 0
If the time zone configured is listed in Table 32, then the starting and ending 
parameters and offset do not need to be configured with this command unless there 
is a need to override the system defaults. The command will return an error if the start 
and ending dates and times are not available either in Table 32 or entered as 
optional parameters in this command.
The following example displays the configured parameters.
A:ALU-1>config>system>time>dst-zone# info

start second sunday april 02:00
end first sunday october 02:00
offset 0

Network Time Protocol (NTP) is defined in RFC 1305, Network Time Protocol 
(Version 3) Specification, Implementation and Analysis. It allows for participating 
network nodes to keep time more accurately and maintain time in a synchronized 
manner between all participating network nodes.
NTP time elements include:
• Authentication-check
• Authentication-key
• Broadcastclient
• MDA-timestamp
• Multicastclient
• Server
CLI Syntax: config>system>time

authentication-key key-id {key key} [hash | 
hash2] {type des | message-digest}
broadcastclient [router router-name] 
{interface ip-int-name} [authenticate]
