TimeShift — Timezone Converter

Ever land on a page full of timestamps in UTC and have to do the math in your head? TimeShift does it for you. Pick the timezone the page is using. Pick the timezone you want to see. Hit convert. Every date and time on the page updates in place with a subtle purple highlight so you can spot what changed. Hover any converted time to see the original. TimeShift finds ISO timestamps, written dates like "Jan 15, 2024 2:30 PM EST", standalone times with timezone labels, and slash-format dates. It handles daylight saving transitions automatically using your browser's built-in timezone database. 40+ timezones organized by region with quick preset buttons for UTC, ET, CT, PT, GMT, JST, and IST. Your last selection is remembered so you don't have to pick again next time. Nothing runs in the background. TimeShift only touches the page when you click the button. No data is collected, no data is sent anywhere, no accounts needed. Everything runs locally in your browser. Built for developers reading server logs, remote teams coordinating across timezones, traders watching international markets, and anyone tired of doing timezone math by hand. Free, no limits.
