UTCTime: UTC and Unix Time

UTCTime shows Coordinated Universal Time and converts timestamps and time zones, entirely on your device. It works offline, needs no account and collects nothing.

NOW
- A live UTC clock with the day of the year and the ISO week number.
- Tap to copy the current time as ISO 8601, Unix seconds, Unix milliseconds or RFC 2822.
- Your local time, its UTC offset and whether daylight saving time is in effect.

CONVERT
- Paste a Unix timestamp in seconds, milliseconds, microseconds or nanoseconds; the unit is worked out from the number of digits.
- Read ISO 8601 and RFC 2822 dates as well.
- Convert a wall clock time from one time zone to another. When a local time is skipped by a spring forward change, or happens twice when the clocks go back, the app says so.

ZONES
- Pin the clocks you check most and put them in your order.
- Search by city, airport code, time zone abbreviation or IANA zone id.
- Ambiguous abbreviations such as IST or CST list every meaning instead of guessing.

SETTINGS
- Dark theme by default, with light and system options.
- 24 hour clock and seconds on or off.

Offsets and daylight saving rules come from your device's own IANA time zone database, so they stay current with system updates. The app asks for no permissions and makes no network requests.
