However, since the case is sealed in plastic, it is apparent that the
native software cannot be adjusted, or revised. The solution will be a
post-it note installed on 11 March noting that 1 hour should be added
to the indicated time.

If it uses WWVB as a reference, your LaCrosse clock should detect the
DST bits appended to the time code and automatically advance (assuming
NIST has been made aware of the Energy Policy Act):

Just curious: what are you planning to do about your sundials?
