SYNC TIME gives the option to set a specific time. To immediately sync time,
highlight SYNC NOW and press enter on the remote.
DST, when set to ON, will make the system clock change automatically with
Daylight Saving Time. If your region does not use Daylight Saving Time, setting
this item to OFF disables the Daylight Saving Time function.
DST Mode can be changed from Auto to Custom. The Energy Policy Act of 2005
changed the time change dates for Daylight Saving Time in the U.S. DST begins
on the second Sunday of March and ends the first Sunday of November. Because
Congress retains the right to revert Daylight Saving Time back to the 1986 time
schedule, certain real-time clock embedded systems need to have the ability to be
changed. The DST Mode can be set from „Auto‟ to „Custom‟. When the DST
Mode is set to „Auto‟, the Daylight Saving Time triggers will conform to the EPA
of ‟05 rules. When the DST Mode is set to „Custom‟, the Daylight Saving Time
triggers can be changed to any of the first, second, third, fourth, or last week of
any month, not overlapping, as shown below.
