What does A.E. mean ?

AE means "Anno Epoche". It is a datation system for globalized informatic era which is supposed to replace older datation systems (e.g. "anno domini", "after hegira" etc.) with a religion-agnostic standard.

AE reference date is 1st January 1970 A.D., also known as UNIX Epoch.

Epoch is already a de facto standard reference date in all dominating programming languages and operating systems.

First project to implement the "AE" datation system was a digital log dedicated to Slovak Presidency of Council of Ministers of European Union which took place during July and December AE46.
