This example shows how to measure elapsed time in a Java program using the Stopwatch API from Google Guava. It creates a started Stopwatch, pauses execution for a random number of milliseconds via `Thread.sleep`, then stops the timer and prints the total duration. The code demonstrates querying elapsed time in nanoseconds, microseconds, and milliseconds using `stopwatch.elapsed(TimeUnit.*)`. The essential API calls are `Stopwatch.createStarted()`, `stopwatch.stop()`, and `stopwatch.elapsed()`, with the output displayed through standard `System.out.println` statements.

Measure.Performance (Simplifies work with Stopwatch class)

This example shows a simplified C# utility for measuring code execution time using the `System.Diagnostics.Stopwatch` class. The `Measure.Performance` method runs a given `Action` code block, records the elapsed milliseconds, and invokes a customizable `WhenDone` callback that defaults to printing the result to the console. The included `Program.Main` demonstrates usage by timing a loop that repeatedly creates and populates a `Dictionary<string, object>`, with the output formatted as `Execution time: {0}ms`. The code highlights how to set a custom reporting action and wrap performance measurement into a concise one-line API.

Stopwatch

A digital stopwatch displays elapsed time in hours, minutes, and seconds, updating every second with a monospace font. The page uses D3.js selection and formatting APIs—specifically `d3.select` and `d3.format`—to update the text content of the body element. A `setInterval` callback increments a counter each second, and the formatted time is rendered as a colon-separated string.

Stopwatch

This example shows a functional stopwatch application with a large digital time display and two buttons, one to toggle between Start and Stop states and another to Reset the timer. The interface is built entirely from reusable components defined with d3.component, and the app’s state is managed through Redux actions like START, STOP, and RESET. The time display updates continuously via d3.timer when running, and the visual formatting converts elapsed milliseconds into hours, minutes, seconds, and centiseconds using d3.format.

DateTime difference between 2 timestamps. Granularity from centuries to nanos.

This example shows the elapsed time between September 11, 2001, and the current moment, broken down into units from centuries down to nanoseconds. Two approaches are compared: the first uses Java’s `ChronoUnit` enumeration with a tail-recursive function to compute differences across twelve granularities, while the second uses `TimeUnit` conversion and `ZoneOffset` to produce a day-to-second breakdown. The Scala code builds a human-readable string, adjusting unit labels for singular values, and prints both outputs from the `Stopwatch` object.

计时器

This example presents a functional digital stopwatch interface built with React. It displays elapsed time in hours, minutes, seconds, and milliseconds within a text input field. Three buttons control the timer: start, stop, and reset. The implementation uses JavaScript's `setInterval` and `clearInterval` to update the display every 50 milliseconds, incrementing time values and handling carry-over between units. The interface is rendered as plain HTML elements with inline event handlers, showing a simple interactive time-tracking tool without external data sources.

Gist c0ec6bb768fd2672307b0807e4ee46fb

This example benchmarks four JavaScript loop styles—a standard `for` loop, a reversed `for` loop, a `for…of` loop, and `forEach`—on a fixed array of ten numbers. It measures execution time by repeating each loop a thousand times via `performance.now()` timestamps, accumulating the total milliseconds. The code defines each loop as a separate function and calls them through a `test` helper, logging the sum to the console. The comparison uses a simple in-memory data array, with no external libraries, focusing on raw loop performance in a JavaScript environment.

简易计时器

This example shows a simple timer interface with a text input displaying elapsed seconds and buttons for start, stop, and reset. The timer updates every second using `setInterval`, toggling an `index` flag to control whether the count increments. Clicking “开始” sets the flag to true, “停止” sets it to false, and “清零” resets both the counter and displayed value. The code directly manipulates the DOM via `document.getElementById` and `value` properties, without using a framework or external libraries.
