High-res timestamps in Node and browser

present

High-res timestamps in Node and browser

Installation

In Node: npm install present

In browser:

1. Copy present.js or present.min.js (with optional source map at present.min.js.map)
2. <script src="path/to/present.{min.}js"></script>
3. performance.now is automatically polyfilled -- if this is undesired, present.noConflict();

Usage

Node only: var present = require('present');

present()

Returns a timestamp in milliseconds. In node, this uses process.hrtime. In the browser, the following are attempted (in order):

• performance.now()
• performance.webkitNow()
• performance.msNow()
• performance.mozNow()
• performance.oNow()
• Date.now()
• new Date().getTime()

present.noConflict()

Browser only. Resets performance.now to what it was before present was included or present.conflict was called.

present.conflict()

Browser only. Polyfills performance.now.
