If every state follows local time then what problems would rise?

If every state follows local time, it could lead to significant confusion and inefficiency, especially in transportation, communication, and commerce. Scheduling conflicts may arise for businesses and services that operate across state lines, as time differences would complicate coordination. Additionally, national events and broadcasts could become challenging to synchronize, affecting media and public engagement. Overall, the lack of a standardized time could disrupt daily activities and hinder economic operations.
