Browser shim for Node.js process.hrtime(). See documentation at nodejs.org

Use hrtime independant of environment (node or browser). It will use process.hrtime first and fallback if not present.

var hrtime = require('browser-process-hrtime')
var start = hrtime()
// ...
var delta = hrtime(start)

You can monkey-patch process.hrtime for your dependency graph like this:

process.hrtime = require('browser-process-hrtime')
var coolTool = require('module-that-uses-hrtime-somewhere-in-its-depths')

This was originally pull-requested against node-process, but they are trying to stay lean.
