Product Documentation, Architecture & Offline Privacy Verification
What It Does
Convert Unix timestamps to readable dates and dates to Unix timestamps with seconds, milliseconds, UTC, and local time support.
How It Works
Key Features
- Seconds & Milliseconds Support: Convert standard Unix timestamps (seconds) or high-precision timestamps (milliseconds) without confusing calculations.
- UTC & Local Timezones: Instantly view timestamps in UTC, standard ISO 8601 formatting, and your exact local timezone.
- 100% Client-Side Privacy: Conversions are performed entirely locally in your browser. No API requests, no tracking, no delays.
Limitations & Compatibility
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is a way to track time as a running total of seconds. This count starts at the Unix Epoch on January 1st, 1970 at UTC. Therefore, the Unix timestamp is merely the number of seconds between a particular date and the Unix Epoch.
What date is Unix timestamp 0?
Unix timestamp 0 corresponds precisely to midnight on January 1st, 1970 in Universal Coordinated Time (UTC).
What is the difference between Unix seconds and milliseconds?
A standard Unix timestamp measures time in seconds since the Epoch. However, many programming languages (like JavaScript) use milliseconds since the Epoch to track time with higher precision. One second equals 1000 milliseconds.
Is Unix timestamp UTC?
Yes, a Unix timestamp fundamentally represents a point in time in UTC. It does not contain timezone information natively, but it can be converted to any local timezone.
Can Unix timestamps represent dates before 1970?
Yes. Dates prior to January 1st, 1970 are simply represented as negative Unix timestamps.
Does this timestamp converter send my data to a server?
No. All conversions happen entirely on your device using native browser date APIs. Your timestamps and dates are never uploaded or tracked.
