5.4.7 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.
