The time zone can affect the display of the current system time. The default value is UTC.
When using SNTP/NTP time servers to update the switch's clock, the time data received
from the server is based on Coordinated Universal T
ime (UTC), which is the same as
Greenwich Mean Time (GMT). This might not be the time zone in which the switch is
located.
