thanks for the contribution.

I really think the addition of a little sse-based live time view does not justify adding (and maintaining) two more example projects. Also, moving the existing examples will break existing links to them (in forum posts or similar)

Please rework the examples to keep the existing folder structure and simply add the live-time view snippets in there. It will be nice to have a little annotation on the page highlighting that the time is actually the "server time" or similar.

lgtm (tiny example fixes are needed, but I'll do them separately)
