Time Zone - When using SNTP/NTP time servers to update the switch's clock, the time data received from the server is based on Coordinated Universal Time(UTC) which is the same as Greenwich Mean Time(GMT).This may not be the time zone in which the switch is located. 'Time Zone' configures a timezone specifying the time difference from UTC time zone. The time zone can affect the display of the current system time. The default value is 'UTC 00:00'
