IP phones maintain a local clock and calendar. Time and date are displayed on the idle
screen of IP phones. Time and date are synced automatically from the NTP server by
default. The NTP server can be obtained by DHCP or configured manually. If IP phones
cannot obtain the time and date from the NTP server, you need to manually configure
them. The time and date display can use one of several different formats.
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 server, you must set
the time zone.
Daylight Saving Time
Daylight Saving Time (DST) is the practice of temporary advancing clocks during the
summertime so that evenings have more daylight and mornings have less. Typically,
clocks are adjusted forward one hour at the start of spring and backward in autumn.
Many countries have used the DST at various times, details vary by location. The DST
can be adjusted automatically from the time zone configuration. Typically, there is no
need to change this setting.
The following table lists available configuration methods for time and date.
