2-2.2 NTP NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an user-defined NTP server as well as Time Zone, the switch will sync the time in a short after pressing button. Though it synchronizes the time automatically, NTP does not update the time periodically without user's 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 come out 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. Web Interface To configure Time in the web interface: 1. Click SYSTEM, NTP. 2. Specify the Time parameter in manual parameters. 3. Click Save. Figure 2-2.2: The NTP configuration Parameter description:  Server 1to 5 : Provide the NTP 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 can only appear once. It can also represent a legally valid IPv4 address. For example, '::192.1.2.34'.  Buttons These buttons are displayed on the NTP page: Save - Click to save changes. Reset - Click to undo any changes made locally and revert to previously saved values. 10
