Chapter 4: Operation of Web- based Management
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 sys-
tem 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 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.

Time
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 adjus-
tment.
Parameter:
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 respec-
tively 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 ser-
ver as well as Time Zone, the switch will sync the time in a short after
pressing <Apply> button. Though it synchronizes the time automati-
cally, NTP does not update the time periodically without user's pro-
cessing.
