All of the UTC Offset drop-downs are configured as UTC plus or minus a set number of
hours.
Examples for the US: For Eastern , choose UTC–05:00; for Central , choose UTC-06:00;
for Mountain , choose UTC-07:00; and for Pacific , choose UTC-08:00.
If you wish to use DST (Daylight Savings Time ["Summer Time"]) rules, click the Use DST
Rules box. Otherwise the time for the local clock will always be standard time.
DST options will appear in the Local Clock window:
Set DST Rules by Region —Check this box to apply regional DST rules. A regions drop-
down menu with the following options will display:
176
EU (Europe )—For if your location complies with the European DST Rule. This rule
differs from all other rules because the DST changes occur based on UTC time, not
local time (all time zones in Europe change for DST at precisely the same time rel-
ative to UTC, rather than offset by local time zone).
US- Canada —For if your location complies with the USA's DST Rule (as it was
changed to back in 2006, where the "DST into" date is the Second Sunday of March
and the "DST out" date is the first Sunday of November).
Australia .
NOTE – If a pre-configured rule DST rule happens to be changed in the future (like
the change to the US DST rule in 2006), this option allows the DST rules to be edited
