What is a Unix Timestamp?
A Unix timestamp is the number of seconds elapsed since January 1, 1970 (UTC). It is a standard, timezone-independent way to represent time in logs, APIs, databases, and distributed systems.
Frequently asked questions
Are timestamps in seconds or milliseconds?+
This tool accepts both. Values under 1e12 are treated as seconds; larger values are treated as milliseconds.
Why does timezone matter?+
The same epoch maps to different local wall-clock times across timezones, but the UTC instant is identical.
Can I use natural date strings?+
Yes. Inputs like ISO 8601, RFC2822, or browser-parseable date strings are supported.
