I am available for full-time remote positions.\n\n# Example\n\n```js\nimport preciseNow from 'precise-now'\n\nconst start = preciseNow()\nconst end = preciseNow()\nconst duration = end - start\n```\n\n# Install\n\n```bash\nnpm install precise-now\n```\n\nThis package works in both Node.js \u003e=18.18.0 and\n[browsers](https://raw.githubusercontent.com/ehmicky/dev-tasks/main/src/browserslist).\n\nThis is an ES module. It must be loaded using\n[an `import` or `import()` statement](https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c),\nnot `require()`. If TypeScript is used, it must be configured to\n[output ES modules](https://www.typescriptlang.org/docs/handbook/esm-node.html),\nnot CommonJS.\n\n# API\n\n## preciseNow()\n\n_Return value_: `number`\n\nReturn the number of nanoseconds since the\n[time origin](https://developer.mozilla.org/en-US/docs/Web/API/DOMHighResTimeStamp#the_time_origin).\n\n# Related projects\n\n- [`time-resolution`](https://github.com/ehmicky/time-resolution): Find the\n  system's time resolution\n\n# Support\n\nFor any question, _don't hesitate_ to [submit an issue on GitHub](../../issues).\n\nEveryone is welcome regardless of personal background.
