NTP:
NTP is Network Time Protocol and is used to sync the network time based
Greenwich Mean Time (GMT). If use the NTP mode and select a built-in NTP time
server or manually specify an user-defined NTP server as well as Time Zone, the
switch will sync the time in a short after pressing <Apply> button. Though it
synchronizes the time automatically, NTP does not update the time periodically
without user’s processing.
Time Zone is an offset time off GMT. You have to select the time zone first and then
perform time sync via NTP because the switch will combine this time zone offset and
updated NTP time to come out the local time, otherwise, you will not able to get the
correct time. The switch supports configurable time zones from –12 to +13 in 1 hour
steps.
Default Time zone: +8 Hrs.
Daylight Saving:
Daylight saving is adopted in some countries. If set, it will adjust the time lag or in
advance in unit of hours, according to the starting date and the ending date. For
example, if you set the day light saving to be 1 hour. When the time passes over the
starting time, the system time will be increased one hour after one minute at the time
since it passed over. And when the time passes over the ending time, the system
time will be decreased one hour after one minute at the time since it passed over.
The switch supports valid configurable day light saving time is –5 ~ +5 step one hour.
The zero for this parameter means it need not have to adjust current time, equivalent
to in-act daylight saving. You don’t have to set the starting/ending date as well. If you
set daylight saving to be non-zero, you have to set the starting/ending date as well;
otherwise, the daylight saving function will not be activated.
Default for Daylight Saving: 0.
