Show posts of a category AND date

Hi,

Is it possible to get posts of a certain category AND a date. Something like this, for example:
http://localhost/?json=get_posts&category_id=23&date=201301&count=20&page=1

Seems to be the only thing missing in this awesome plugin unless i’m missing something.

Thanks,

Grant
