Unix timestamps
Unix time counts seconds since January 1, 1970 00:00:00 UTC — the "Unix epoch." Developers use it in APIs, databases, and log files because it is timezone-neutral at storage time. Display always requires picking a timezone for humans.
Some systems store milliseconds instead of seconds — 13-digit values are milliseconds; 10-digit values are seconds. This tool auto-detects based on magnitude.
Example: 1722384000 seconds = July 31, 2024 00:00:00 UTC. To convert back, pick a local date and time — the Unix value depends on your timezone offset from UTC.
Common questions
Seconds or milliseconds?
Values above 1,000,000,000,000 are treated as milliseconds. Smaller values are treated as seconds.
What timezone is used?
Conversion displays in your browser's local timezone. Unix storage is UTC-based; always confirm timezone when debugging production logs.
