The language was conceived in May 2016, as a possible answer to the question "What would be next step along from the Unary language (or other 0-dimensional languages)?".
Nullary is a computer language that takes no user input. A correct implementation of Nullary takes no program and no parameters from the user.
Upon launch, a Nullary implementation takes note of the elapsed time since the epoch (in the current timezone) measured in microseconds (denoted T).
If Nullary doesn't output something exciting in a quick enough time, you can turn off your computer.
Needless to say, Nullary isn't a very practical language. It may be of use to time travellers with a warped sense of humour, or those of a very patient disposition.
Language Variant: Nullary+
Instead of using Unary, translate T into base 8 and use it as Brainfuck input. This variant has the advantage of not having the input parsing delay that Unary/Progressive Unary has.
