Connaissance Des Temps

The Connaissance des temps (English: Knowledge of Time) is an official yearly publication of astronomical ephemerides in France. Until just after the French Revolution, the title appeared as Connoissance des temps, and for several years afterwards also as Connaissance des tems.
