Setting the Time Zone
Use the System > Time (Configure Time Zone) page to set the time zone. SNTP uses
Coordinated Universal Time (or UTC, formerly Greenwich Mean Time, or GMT)
based on the time at the Earth’s prime meridian, zero degrees longitude, which
passes through Greenwich, England. To display a time corresponding to your local
time, you must indicate the number of hours and minutes your time zone is east
(before) or west (after) of UTC. You can choose one of the 80 predefined time zone
definitions, or your can manually configure the parameters for your local time zone.
Parameters
The following parameters are displayed:
◆

local time zone.
