[CQ-Contest] CWSS and daylight savings time

[Richard DiDonna NN3W]

It wont change propagation in general, but it COULD affect decisions on band changes.  Under old time change standards, folks on the east coast get perhaps 1 hour of good run time on the high bands before folks start to transition to 40  meters.  In 2006, the sun sets at 5:39 p.m., which means that 40 meters is already viable by 2100z and skip is lengthing quickly, but folks tend to linger to max mults and QSO counts  in the Plains and on the Left coast.  By contrast, in 2007, sunset is not until 6:40 p.m. which means closer to 2 hours of high band operating time.

There is a nuance here.
