Date on Phone UI.
Type To select how to configure time. It could be set manually
or get from Internet automatically via NTP server.
Manual: To set Time and Date manually.
Auto: To get Time via NTP server.
If user sets time to be Manually, it will only
take effect till the next reboot; after reboot,
the phone will switch to Auto mode
automatically because there is no way for IP
phone to record time during power off.
NTP To configure NTP server related settings.
Time Zone: To select local Time Zone for NTP server.
Primary Server: To configure primary NTP server address.
Secondary Server: To configure secondary NTP server
address; it takes effect if primary NTP server is
unreachable.
Update Interval: To configure interval between two
consecutive NTP requests.
Network Time Protocol (NTP) is used to
automatically synchronize local time with
Internet time, since NTP server only responds
to GMT time, so that you need to specify the
Time Zone for IP phone to decide the local
time.
Daylight Saving
Time To display or configure DST settings.
DST is short for daylight saving time, which
means the time on the summer days when the
sun rises early will be adjusted forward to save
daylight. The DST will take effect during the
period that is set by user. (All the settings for
DST are all self-explanatory. Please consult
with your administrator for local DST details.)
