Summary
This tool displays live, auto-updating clocks for every major US time zone — Eastern, Central, Mountain, Pacific, Alaska, and Hawaii — in a single view. Each card shows the current local time, date, UTC offset, and whether Daylight Saving Time is currently active. No configuration needed; the page detects DST automatically using the browser's Intl API.
How it works
- The page loads and immediately reads your browser clock.
- JavaScript formats the current moment into each US time zone using the Intl.DateTimeFormat API.
- DST status is computed by comparing the current UTC offset with the zone's standard (winter) offset.
- A setInterval updates every card once per second so the displayed times stay current.
- Clicking any card copies the displayed time to your clipboard.
Use cases
- Schedule a meeting or call across multiple US regions.
- Check whether a city on the other side of the country is still in business hours.
- Confirm current DST status before booking a flight or setting an alarm.
- Quickly see what time it is in Hawaii or Alaska without mental arithmetic.
- Developers debugging timestamp issues across US data centers.
- Remote teams coordinating stand-ups across East and West Coast offices.
