Time & Date
The IP phones maintain a local clock. By default, a digit clock widget will be displayed on the home screen when
the IP phone starts up. You can check the current time and date on the home screen. You can also check the
current time and date on the control center. In addition, phone’s time will be also displayed on the right of the status
bar. You can check the current time on the three idle screens.
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.
In this case, if the Manual Time option is also disabled (see the web interface) and the IP phone receives
date and time in 200 OK SIP response from the SIP server, then the IP phone will automatically update the
time as obtained from the SIP server. To update the time from the NTP server next time (provided the NTP
server is functional and the IP phone can query for the updated time from the NTP server), you must restart
the IP phone.
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.
