No, and also the other page was pure HTML and CSS. This clock is using React and Javascript, so it's not a fair comparison.
This isn't using the same prompt or stack as the page from that post the other day; on aistudio it builds a web app across a few different files. It's still fairly concise but I don't think it's that much so.
It also includes javascript which was verboten in the original prompt, and doesn't specify the time the clock should be set too.
