This is from "Datum Centurio" by David F. Wallace. "DATUM CENTURIO From <Leckie & Webster's Connotationally Gender-Specific Lexicon of Contemporary Usage>, a 600gb DVD3 Product with l.6gb of Hyperavailable Hot Text Keyed to 11.2gb of Contextual, Etymological, Historical, Usage, and Gender-Specific Connotational Notes, Available Also with Lavish Illustrative Support in All 5 Major Sense-Media*, c2096 by R. Leckie DataFest Unltd." This is the intro of the short story by Wallace. It's a future dictionary's entry on "date." I don't get the meaning of "Datum Centurio". What does "centurio" mean in this context. Anyone who has read this story, please give me some suggestion.
