Time Zone
A time zone is a region on the 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 need to
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 near the start of spring and are adjusted
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.
Usually there is no need to change this setting.
