Lap 3 tells you nothing six weeks later. "The hill" tells you everything. How lap naming works in TiCaNo Stopwatch v1.7.0 — where the names travel, how to correct the record, and why the same three taps work for a Saturday morning as well as a set of intervals.
In October 1884, 41 delegates from 25 nations met in Washington to pick one zero for the whole world. The vote was 22 to 1 — and one of the two countries that abstained held out for 27 years.
Your thumb takes about 200 milliseconds. Your phone's screen adds 100 more. A guide to timing things well anyway — what the numbers mean, which errors cancel, and which ones quietly don't.
Cooking, practising, training, timing an experiment, logging a work session — what each one looks like in TiCaNo, feature by feature, boundary by boundary. No countdown promises: the app times up, and that turns out to be the point.
Until 2008, the official style manual of the United States government said 12 a.m. meant noon. It had it backwards, or forwards — and the bodies that have ruled since all agree on one thing: don't write it.
00:04.2137 — that last digit is real, not padding. It is also not an accuracy claim. The difference between resolution, precision and accuracy, told through our own app's code.
In 2018, every mains-powered clock in Europe lost six minutes because the grid drifted by four thousandths of a hertz. No phone noticed. The difference is correction — and the correction is also the one thing that can touch a running stopwatch.
The energy savings round to zero, the heart-attack spike is real but almost always misquoted, and the sleep-medicine consensus recommends the opposite of what the US House just voted for. What the studies actually measured.
In June 1955 the steadiest timekeeper on Earth began ticking — and nothing steady enough to check it against existed. So it was tied to Greenwich, then to the Moon, and finally defined.
In Kashgar, the sun can reach its highest point at ten past three in the afternoon. That is not astronomy — it is politics, and once you see it, the whole map of time makes sense.
