Why Time Shuttle

Bidirectional Conversion

Convert Unix timestamps to human-readable dates and vice versa. Supports both seconds and milliseconds.

100% Private

All conversions happen in your browser using native Date and Intl APIs. No data is ever uploaded.

Multi-Format Output

See the same moment as Unix (s), Unix (ms), ISO 8601, RFC 2822, UTC string, and localized date — all at once.

Timezone Converter

Convert dates between any timezones using the full IANA timezone database. No hardcoded offsets.

Relative Time

Instantly see '3 hours ago' or 'in 2 days' with Intl.RelativeTimeFormat, localized for English and Chinese.

Free Forever

No limits, no ads, no hidden fees. Full-featured timestamp toolkit at zero cost.

How It Works

Enter Timestamp or Date

Type a Unix timestamp (seconds or milliseconds) or a human-readable date in the input field

See All Formats

The tool instantly shows the same moment in every format — Unix, ISO 8601, RFC, UTC, localized, and relative

Copy or Convert

Copy any result with one click, or use the timezone converter to see the time in a different zone

The Complete Timestamp Toolkit for Developers

Unix timestamps are the universal language of computing. From database records and API responses to log files and cache headers, timestamps are everywhere. But converting between Unix time and human-readable dates, handling timezone differences, and calculating relative time intervals are tasks developers face daily. Time Shuttle brings all these capabilities together in a single, fast, privacy-focused interface.

Unlike other online timestamp tools that send your data to remote servers, Time Shuttle performs every conversion entirely in your browser using native JavaScript Date and Intl APIs. Your data — whether it's API timestamps, database records, or log entries — never leaves your device. Support for all IANA timezones, automatic seconds/milliseconds detection, batch conversion, and real-time 'now' display make it the fastest way to handle time-related tasks.
