Setting the Time Zone Use the System > Time (Configure Time Server) 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 west
(before) or east (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.
