For UTC offset purposes only the November deadline matters, since the 
March change would be a no-op. For the less-important timezone 
abbreviation and tm_isdst flag, both deadlines matter.

My Maryland contacts are pretty limited, unfortunately. Perhaps you know 
people at NIH who might be able to help? There are medical implications 
of fooling with clocks on short notice: this was an issue in 2007, the 
last time the US changed the rules (see, for example, 
<https://doi.org/10.1177/2374289518784222>), and I'd expect even more 
problems if Maryland changes with less notice than there was in 2007.

Do you know Freeman Hrabowski, or know anybody who knows him? Although 
he's retiring from UMBC in July, a word from him might go far. Another 
possibility would be the NIST Gaithersburg Group; although the NIST Time 
Realization and Distribution Group is in Boulder I expect there's 
somebody in Maryland with metrology expertise and/or contacts.
