A.5.6. Configuring Daylight Saving Time
Two independent check boxes control Daylight Saving Time (DST) in MetaCast 2. The first check box
is used to set the DST Flag in the 8083XDS-AD and is checked when Daylight Saving Time is currently
being observed. It is located on the Clocks page and in most cases it should be updated by MetaCast
2's automatic DST adjustment controls. The second check box is used to set the DSO Flag in the
8083XDS-AD and needs to be checked if the current region you are broadcasting to observes Daylight
Saving Time. MetaCast 2, and any televisions or VCRs receiving XDS Time of Day packets, use the
DSO Flag to determine if they should adjust their time when the DST Flag is set.
Even in regions that do not observe Daylight Saving Time, you must still turn on
the DST flag in accordance with surrounding regions so that they can properly
calculate their local time.
The status of both check boxes can be monitored on the Clocks page. When Daylight Saving Time is
active, the box next to the text 'Daylight Saving Time in Effect' will become checked. For regions that
do not observe Daylight Saving Time, the comment '(Not observed in this region)' will be added to the
checkbox caption.
You can choose how MetaCast 2 adjusts for DST on the Date/Time Properties page. The check box
immediately below the time zone list shows if DST is observed in your region. This value is updated
from the Windows' Time Zone database whenever you select a new time zone. You should normally
use the default Windows value for this check box. If this check box is checked incorrectly then you
probably do not have the correct windows Time zone selected.
