Does WWVB switch to DST, or, just set a bit in the data stream telling
the device that receives the signal that DST is active?
I seam to remember (that is dangerous) that WWVB data has GMT time
encoded into the data stream and that it is up to the receiving device
to display the correct offset from GMT.
My buddy, Google, found the data WWVB transmits here:
http://www.nist.gov/pml/div688/grp40/wwvbtimecode.cfm
Hope this helps
