What is Unix time?
Unix time counts seconds from January 1, 1970 at 00:00:00 UTC. Negative values represent earlier dates. Unix time does not count leap seconds.

THE SHORT VERSION
A timestamp is a point in time.
A time zone is a way to read it.
Seconds, milliseconds, or microseconds?
Contemporary timestamps usually have 10, 13, or 16 digits respectively. Auto-detection uses this heuristic, not a guarantee: choose the unit explicitly for historical or far-future dates. Microsecond precision is preserved.
Why does the same timestamp show a different hour?
The instant stays the same; the displayed clock time depends on the selected zone and its daylight saving rules. ISO input needs an explicit offset, such as 2026-09-05T14:00:00+02:00, to avoid ambiguity.
Working with logs
Paste one timestamp or ISO date per line. Mixed units work in auto mode. Invalid lines stay visible so you can fix the source. CSV exports include both UTC and your selected zone. Limit: 5,000 lines per batch.
