The value specified for longitude may be adjusted to correct for areas, such as Nova Scotia, where
the local time differs from Greenwich Mean Time by a non-hourly amount. The calculated time
of sunrise/sunset will change by four minutes for every degree change in longitude. To cause the
calculated sunrise/sunset to occur later, enter a larger value for longitude. Enter a smaller value
for longitude to cause the time to occur earlier.
It is not necessary to alter the time zone to compensate for daylight savings time, the Model 925
will automatically adjust its calculations for sunrise and sunset, and time when daylight savings
time begins and ends.
