We report a real-time determination of the present moment, accurate to the nearest second. The method requires no apparatus beyond a system clock, and the result is reproducible by any observer sharing the reader's time zone.
Keywords: chronometry, real-time analysis, the present
Let h, m, s ∈ ℤ denote the current hour, minute, and second respectively, each updated automatically as the ambient moment advances.
Theorem 2.1 (The Present Moment). At the time of reading, the following holds:
Proof. Immediate by observation of the system clock.∎
Corollary 2.2 (The Present Date). —.
