Title: Unused code in tz.js

The following block of code

```
if (opts.async) {
if (typeof opts.success !== 'function') return;
opts.error = opts.error || console.error;
return fs.readFile(opts.url, 'utf8', function (err, data) {
return err ? opts.error(err) : opts.success(data);
});
}
```

is untested, and doesn't seem to be used by any of our code (only the synchronous line underneath is called). If this is true, the block should be removed.
