NTP provides Coordinated Universal Time (UTC). No information about time zones or
daylight saving time is transmitted; this information is outside its scope and must be
obtained separately.
UDP Port: 123.
Daylight saving is a period from late spring to early fall when many countries set their
clocks ahead of normal local time by one hour to give more daytime light in the evening.
Notes:
1. The SNTP server always replies the UTC current time.
2. When the Switch receives the SNTP reply time, the Switch will adjust the time
with the time zone configuration and then configure the time to the Switch.
3. If the time server’s IP address is not configured, the Switch will not send any
SNTP request packets.
4. If no SNTP reply packets, the Switch will retry every 10 seconds forever.
5. If the Switch has received SNTP reply, the Switch will re-get the time from NTP
server every 24 hours.
6. If the time zone and time NTP server have been changed, the Switch will repeat
the query process.
7. No default SNTP server.
