Monotonically increasing timestamp.

<img src=https://secure.travis-ci.org/'Dominic Tarr'/monotonic-timestamp.png?branch=master>

This is NOT a accurate representation of the time. Since js only measures time as ms, if you call Date.now() twice quickly, it's possible to get two identical time stamps.

monotonic-timestamp fixes that problem! (crudely)

var timestamp = require('monotonic-timestamp')

console.log(timestamp())
console.log(timestamp())
console.log(timestamp())
console.log(timestamp())
console.log(timestamp())

subsequent calls to timestamp() are ALWAYS strictly ordered.

My precious bytes! wasted on your timestamp!

pack it into a string!

timestamp().toString(36) 

if you want a constant-length string, you can use monotonic-timestamp-base36

of course, if you are using a binary protocol, it will be cheaper to use the float...
