Signamax 065-7840 24-Port 10/100/1000BaseT/TX Managed Switch

NTP:

NTP is Network Time Protocol and is used to sync the network time

based upon Greenwich Mean Time (GMT). If you use the NTP mode and

select a built-in NTP time server or manually specify a user-defined NTP

server as well as a Time Zone, the switch will sync the time shortly after

pressing the <Apply> button. Though it synchronizes the time

automatically, NTP does not update the time periodically without user

processing.

Time Zone is an offset time from 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 the updated NTP time to determine the local

time, otherwise you will not able to get the correct time. The switch

supports configurable time zones from –12 to +13 1 hour steps.

Default Time zone: + 8 Hrs.

Daylight Saving:

Daylight savings time is adopted in some countries. If set, it will adjust

the time lag or advance in units of hours, according to the starting date

and the ending date. For example, if you set the daylight 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 the switch need not

adjust the current time, which is equivalent to inactive daylight saving.

You do not 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.
