A time server is a computer server that reads the actual time from a reference clock and
distributes this information to the clients in a network. The Network Time Protocol (NTP) is
the most widely used protocol that distributes and synchronizes time in the network.
The IP phones synchronize the time and date automatically from the NTP time server by
default. The NTP time server address can be offered by the DHCP server or configured
manually. NTP by DHCP Priority feature can configure the priority for the IP phone to use
the NTP time server address offered by the DHCP server or configured manually.
Time Zone
A time zone is a region on Earth that has a uniform standard time. It is convenient for
areas in close commercial or other communication to keep the same time. When
configuring the IP phone to obtain the time and date from the NTP time server, you must
set the time zone.
