2-1.3 NTP
NTP is Network Time Protocol and is used to sync the network time based on Greenwich Mean
Time (GMT). If you use the NTP mode and select a built-in NTP time server or manually specify
a user-defined NTP server as well as Time Zone, the switch will sync the time shortly after
pressing the <Apply> button. Though it synchronizes the time automatically, NTP does not
update the time periodically without user processing.
Time Zone is an offset time off GMT. You have to select the time zone first and then perform
time sync via NTP because the switch will combine this time zone offset and updated NTP time
to set the local time. Otherwise, you will not able to get the correct time. The switch supports
configurable time zone from –12 to +13 step 1 hour.
Default Time zone: +8 Hrs.

Provide the SNTP IPv4 or IPv6 address of this switch. IPv6 address is in 128-bit records
represented as eight fields of up to four hexadecimal digits with a colon separating each
field (:). For example, 'fe80::215:c5ff:fe03:4dc7'. The symbol '::' is a special syntax that can be
used as a shorthand way of representing multiple 16-bit groups of contiguous zeros; but it
