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 with some time
reference. Because time usually just advances, the time on different node stations
might 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 the SNTP function to get the time from the SNTP
server.

Daylight Saving Time: This function is used to enable/disable Daylight Saving
Period and Daylight Saving Offset fields.

