Parameter description:
y Current Time: Show the current time of the system.
y Manual:
This is the function to adjust the time manually. Filling the valid figures in the fields of Year, Month, Day,
Hour, Minute and Second respectively and press <Apply> button, time is adjusted. The valid figures for
the parameter Year, Month, Day, Hour, Minute and Second are >=2000, 1-12, 1-31, 0-23, 0-59 and
0-59 respectively. Input the wrong figure and press <Apply> button, the device will reject the time
adjustment request. There is no time zone setting in Manual mode.
y 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
zone from –12 to +13 steps 1 hour.
Default Time zone: +8 Hrs.
y 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.
