Extended world clock

The world clock page is a personal board — a handful of cities you choose, shown large with analog faces. This page is the opposite: every city the site covers, in one dense table you can sort and filter. Use the world clock for the places you check daily and this page when you need to scan everywhere at once.

Yes. The sort control offers city name, country, current local time and UTC offset. Sorting by offset gives you a west-to-east sweep of the world; sorting by local time groups everywhere that happens to share a clock reading right now, regardless of which zone they are in.

Because a clock reading does not identify a zone. At any moment dozens of places read the same hour and minute while sitting at different offsets from UTC — and they will diverge the next time one of them changes its clocks. The offset column is the one that tells you what is actually going on.

The full table is in the page as served, so every city, time, date, offset and abbreviation is readable and searchable without scripts — accurate as of the build time shown above it. Sorting, filtering and the ticking second are the parts that need JavaScript.
