1305, has been adopted on the system is version 3 protocol. The switch pro-
vides four built-in NTP server IP addresses resided in the Internet and an user-
defined NTP server IP address. The time zone is Greenwich-centered which
uses the expression form of GMT+/- xx hours.
Function name: Time
Function Description: Set the system time by manual input or set it by syn-
cing from Time servers. The function also supports daylight saving for dif-
ferent area's time adjustment.
Parameter Description:
Current Time: Shows the current time of the system.
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.
Default: Year = 2000, Month = 1, Day = 1, Hour = 0, Minute = 0,
Second = 0
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 com-
bine 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 step 1 hour.
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
