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 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.
