The Time Screen
Select the
Time
tab to set up your local offset, and daylight saving time (DST) preferences. Local
offset should not change, and is the difference between UTC and your local standard time. For
example, Pacific Standard Time is -8 hours, and Singapore is +8 hours. H1owever, DST advances
the time by one hour, and removes the hour advance each year. DST can be turned Off, On, or set
to Auto for automatic changeovers in your specific locale. The default AUTO DST occurrence is
set for North America.

Daylight Saving Time
The daylight saving time settings change when selecting
Auto
by adding some new windows to select
the start and stop date and time. The start and stop times are given in minutes after midnight.
The start and stop dates are chosen by the week and weekday of the start and stop month.
DST Background
In 2007 the U.S. Federal Government changed the start and stop dates to increase the number of
days allotted to DST. Prior to the change, DST started at 2:00 a.m. the first Sunday of April and
ended at 2:00 a.m. on the last Sunday of October. Currently, DST starts at 2:00 a.m. on the
second Sunday of March and ends at 2:00 a.m. on the first Sunday of November. The result is an
additional 4 to 5 weeks allotted to DST, depending on the specific year.
Since individual countries and regions have their own names, times and dates for the same effect
as DST, the clock was designed to adjust for all these differences around the earth.
