title: JavaScript Datetime picker without jQuery?
body: <p>I need to have my users select a date and time in one of my forms, and I don't want to spend time reinventing the wheel to create a <code>datetime picker</code> in JavaScript. The problem is that the only "pickers" I can find online are all based on jQuery, which normally wouldn't be a problem except that the entire site is practically finished without using jQuery at all. So it would feel stupid to use that entire giant framework now when all I need it for is a single input on one form on one page of my site.</p>
