browser-process-hrtime
Browser shim for Node.js process.hrtime(). See documentation at nodejs.org
usage
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)
monkey-patching
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')
note
This was originally pull-requested against node-process, but they are trying to stay lean.
