NTP Time Server
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.
