A “long hour” refers to the “decimal hour”, equal to 2.4 hours, exactly one tenth of a day, sometimes called a “deciday”. The decimal hour was an official unit of French Decimal Time, during the French Revolution, during the 1790s. Since then there are periodic attepts to revive it. It sometimes features in scifi to represent a futuristic or alternate system of measurement.

Principal: well lets just see what happens.
