DC's Other Half — Maryland's Federal Clockwork

Maryland hosts more federal agencies per square mile than any state. The NSA (Fort Meade), NIH (Bethesda), FDA (Silver Spring), NASA Goddard (Greenbelt), and NIST — the agency that literally defines official US time — are all in Maryland. The state runs on federal government time.

NIST (National Institute of Standards and Technology) in Gaithersburg, Maryland maintains the official US time standard using cesium atomic clocks accurate to 1 second per 300 million years. When your phone auto-syncs time, it ultimately traces back to Maryland.

The Baltimore-Washington corridor is one of the wealthiest regions in America. Maryland has the highest median household income of any US state — driven by the concentration of federal workers, defense contractors, and biotech researchers who commute on ET.
