From NSwiki, the NationStates encyclopedia.
A.C.E. - Arizonan Common Era
A.C.E. is the current time period of Arizona Nova and the standard reckoning used to determine the position of events in Arizonan history. It was instated after the defeat of the slavers over the skies of Arizona Nova, and marks the boundary between Arizona Nova as a planetbound nation and Arizona Nova as an interstellar power.
