6.10 SNTP Configuration
SNTP (Simple Network Time Protocol) is a simplified version of NTP which is an Internet
protocol used to synchronize the clocks of computers to some time reference. Because time
usually just advances, the time on different node stations will be different. With the
communicating programs running on those devices, it would cause time to jump forward
and back, a non-desirable effect. Therefore, the switch provides comprehensive
mechanisms to access national time and frequency dissemination services, organize the
time-synchronization subnet and the local clock in each participating subnet peer.
Daylight saving time (DST) is the convention of advancing clocks so that afternoons have
more daylight and mornings have less. Typically clocks are adjusted forward one hour near
the start of spring and are adjusted backward in autumn.
 SNTP Client: Enable/disable SNTP function to get the time from the SNTP server.
 Daylight Saving Time: This is used as a control switch to enable/disable daylight
saving period and daylight saving offset. Users can configure Daylight Saving Period
and Daylight Saving Offset in a certain period time and offset time while there is no
need to enable daylight saving function. Afterwards, users can just set this item as
enable without assign Daylight Saving Period and Daylight Saving Offset again.
 UTC Timezone: Universal Time, Coordinated. Set the switch location time zone. The
following table lists the different location time zone for your reference.
