Package Exports

set-now

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (set-now) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

set-now

Adds Date.setNow() to JavaScript's global Date object.

This is useful for making tests deterministic. Wind back the clock to a time in the past (or in the future).

Install

npm install set-now

Date.now() // 1458216000000

// wait 1 second
setTimeout(function () {
  new Date() // Thu Mar 17 2016 08:00:01 GMT-0400 (EDT)
  Date.setNow() // reset the time back to normal
  new Date() // today's actual date
}, 1000)
