3-1-3. Time Configuration
The switch provides manual and automatic ways to set the system time via
NTP. Manual setting is simple and you just input “Year”, “Month”, “Day”, “Hour”,
“Minute” and “Second” within the valid value range indicated in each item. If you
input an invalid value, for example, 61 in minute, the switch will clamp the figure to
59.
NTP is a well-known protocol used to synchronize the clock of the switch
system time over a network. NTP, an internet draft standard formalized in RFC 1305,
has been adopted on the system is version 3 protocol. The switch provides 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 syncing from Time servers.
The function also supports daylight saving for different area’s time adjustment.
Parameter description:
Current Time:
Show 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 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 step 1 hour.
Default Time zone: +8 Hrs.
