Frequently Asked Questions

What is a Unix timestamp?
A Unix timestamp is the number of seconds (or milliseconds) that have elapsed since January 1, 1970 00:00:00 UTC, known as the Unix epoch. It is a universal way to represent time that is independent of time zones.
What is UTC vs local time?
UTC (Coordinated Universal Time) is the global standard with no timezone offset. Local time is adjusted for your timezone. Timestamps are always stored in UTC but displayed in local time for convenience.
Is this tool affected by my timezone?
The tool shows both UTC and your local timezone. Timestamps are timezone-independent, but the human-readable conversions use your browser's timezone settings.
Seconds or milliseconds?
Traditional Unix timestamps are in seconds (10 digits, e.g., 1704067200). JavaScript and many modern APIs use milliseconds (13 digits, e.g., 1704067200000). This tool auto-detects the format.
What is ISO 8601 format?
ISO 8601 is an international standard for representing dates and times. Example: 2024-01-01T00:00:00.000Z. The Z indicates UTC, or you can use an offset like +05:30.
