+# browser-process-hrtime
+
+Browser shim for Node.js `process.hrtime()`.
+See [documentation at nodejs.org](http://nodejs.org/api/process.html#process_process_hrtime)
+
+This module does not provide the same level of time precision as node.js, but provides a matching API and response format.
+
+### usage
+Use hrtime independent of environment (node or browser).
+It will use `process.hrtime` first and fallback if not present.
+```js
+const hrtime = require('browser-process-hrtime')
+const start = hrtime()
+// ...
+const delta = hrtime(start)
+```
+
+### monkey-patching
+You can monkey-patch `process.hrtime` for your dependency graph like this:
+```js
+process.hrtime = require('browser-process-hrtime')
+const coolTool = require('module-that-uses-hrtime-somewhere-in-its-depths')
+```
+
+### note
+This was originally pull-requested against [node-process](https://github.com/defunctzombie/node-process),
+but they are trying to stay lean.
