Commonly read as "tee zero." [Internet slang], used primarily by the programming/cracking/hacking crowd – though its use among gamers has become more widespread lately. Meanings: 1). the beginning 2). since the beginning 3). at the beginning 4). preemptively Synonyms: all along, from the start, preemptively, beforehand Origins: Contrary to the belief of some, the etymology of t0 is probably unrelated to NASA's MET system (see tminus). Rather, it more likely has origins in the statement t = 0, in this case [representing] the time at which a [particular] event began.
