Epoch → date

Date → epoch Display and interpret in IANA time zone

For a local time skipped by a daylight-saving change, the date cannot be converted. A repeated fall-back time can refer to either occurrence.

What is a Unix timestamp?

A Unix timestamp (epoch time) counts the seconds elapsed since 1 January 1970 00:00:00 UTC, ignoring leap seconds. It is a compact, time-zone-independent way to store moments in databases, logs and APIs.

Seconds, milliseconds, microseconds or nanoseconds?

JavaScript and Java commonly use milliseconds. Some databases and high-resolution clocks use microseconds or nanoseconds. Choose the unit explicitly when known; auto-detection is only a size-based estimate. JavaScript dates display millisecond precision.

Time zones and daylight saving

The selected IANA time zone controls display and interpretation of date-time inputs. A wall time skipped by a daylight-saving transition cannot be converted. During a repeated fall-back hour, the same wall time can represent two different instants.

Systems storing the timestamp as a signed 32-bit integer overflow on 19 January 2038 at 03:14:07 UTC. Modern 64-bit systems are not affected.
