Why we need picker.time reference in translations?

I've got `Uncaught TypeError: Cannot read property 'defaults' of undefined` in my translation file.
I've looked there

```
jQuery.extend( jQuery.fn.pickatime.defaults, {
clear: 'удалить'
});
```

I don't need `picktime` in my application and don't want to include it?
Can we split that to additional translation file?
