The time of the author can be perceived as meaning the perception of the program, as you see it before compilation, which does not foresee the values of variables at runtime, as with user input. In the context of software intended for developers, this can be exacerbated in meaning with added levels of complexity. Having one name or another caused by someone traveling abroad and using the toilet will vary in uncertainty, but may possibly relate to their idea of leaving abroad to be perceived as a difference in customs.
I read the following sections of the book, and the author’s time, apparently, is not a recognized scientific term, but, apparently, its opposite of execution time, becomes an all the more living creature subject to author’s time, a “philosophical” manifestation that may include himself some disagreement The third party mentions this, placing it in exotic conditions, from which the third party may not have had accurate foresight.
There are rules for how the compiler finally interprets this, and although you can understand what that will mean. The utility comes from a compiler who calls this person a crime at the police station (this is the execution time).
