FAQ

What is a Unix timestamp?

A Unix timestamp is the number of seconds elapsed since January 1, 1970 00:00:00 UTC (known as the Unix Epoch). It's the most universal time representation in computer systems, unaffected by timezone or language.

What's the difference between second and millisecond timestamps?

Second-level timestamps are precise to seconds (10 digits), while millisecond-level are precise to milliseconds (13 digits). JavaScript's Date.now() returns milliseconds, while most backend APIs use seconds. This tool auto-detects and converts.

What date formats are supported?

Supports ISO 8601 (2026-07-28T10:30:00Z), RFC 2822 (Mon, 28 Jul 2026 10:30:00 GMT), custom formats (yyyy-MM-dd HH:mm:ss), and 20+ other formats.

Are the conversion results accurate?

Conversion results are 100% accurate, based on the browser's native Date object and international standard timezone database. Supports leap second handling and automatic daylight saving time adjustment.

How to use timestamps in different programming languages?

The tool includes timestamp handling examples for various languages including JavaScript, Python, Java, Go, PHP, Ruby, making it easy for developers to copy and use directly.
