Show HN: I made a mini site to see timezone shifts (opens in new tab)

Hey HN. I made a micro site one recent evening to see upcoming (and recent past) timezone transitions. At my job, we have some timezone specific code where we often see spikes in metrics due to random timezone shifts around the world. Just for fun, I wanted a way to easily see where and what this timezone shift might have been, so built this mini site to do so.

Its fully clientside and works by making use of the Internationalization API, so if you need an API for this you're coming to the wrong place, but feel free to yoink the code.

Its just one fat index.html file. Served off my VPS via caddy file server. No dependencies or build steps. See the code in the github link below.

All the CSS is "vibe coded", I think it looks pretty cool.

As an aside, I love that AI has made it so easy to spit out sites like this. My personal site is filled with subdomains like this one with little random tools which I occasionally use.
