Help with the UTC Swap iOS app and utcswap.com
UTC Swap converts a UTC date and time to local time in any timezone — or the other way around. Pick a date and time, choose a timezone, and the result updates instantly. Everything runs on your device; no account and no internet connection needed.
Use the toggle at the top: UTC → Local converts a UTC time into any timezone; Local → UTC reads your entered time in the selected timezone and shows the UTC equivalent. Switching direction keeps the same moment in time, so the result stays consistent.
Your device's current timezone. Tap the timezone field to choose any other IANA timezone — the list is searchable, and each entry shows its current GMT offset. Reset to my timezone brings back the default.
Yes. Conversions use the timezone database built into iOS (and your browser, on the web), so GMT offsets and DST transitions are always accurate — including historical and future dates.
Because it doesn't need any. UTC Swap makes no network requests and collects no data — see the privacy policy.
