Alarm Clocks - Garmin GPS 100 Owner's Manual

The GPS 100 will keep track of local as well as UTC time. UTC, which is
essentially the same as Greenwich Mean Time (GMT), does not change with
local time zones. It is the time at 0 degrees longitude which passes through
the city of Greenwich, England.
UTC time is set on the Initialization Page. While navigating, the GPS 100 will
automatically correct UTC time with accurate information received from the
satellites. Due to the irregular nature of time zones, the unit does not attempt
to correct your local time when you pass from one time zone to another. If
you cross a time zone boundary, update the local time manually.
To enter your local date and time...
· Move the cursor over the local date field and enter your local date.
· Move the cursor over the local time field and enter your local time in
24 hour format.
