Setting 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.
