I’m *sure* :) that the embedded information in the chip takes care of all that stuff
correctly …. 

On a side note, my Citizen WWVB watch missed the change to DST this year. 
I still had it set to European time and it was not able to figure out which system
to update to. I suppose it also may have been looking for DCF77 rather than WWVB.

Multiple time zone stuff is *not* simple.
