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
enable this without assigning 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.
