Directs NASA, working with the White House Office of Science and Technology Policy, to lead creation of a coordinated lunar time standard and an implementation strategy. It recognizes that current Earth-based time (UTC) has limits for Moon and deep-space operations.

The strategy must keep time traceable to UTC, precise enough for navigation and science, resilient if contact with Earth is lost, and expandable to missions beyond the Earth–Moon system. NASA must brief two congressional committees on the plan within two years of enactment, coordinating with other federal agencies, industry, academia, and international partners and standards bodies.
