Everyday tools / Unix Timestamp Converter
Convert Unix timestamps and ISO 8601 dates across time zones locally.
ISO input requires Z or an explicit UTC offset; the time zone controls the displayed result.
Choose seconds, milliseconds or ISO 8601 with an explicit UTC offset. Enter an IANA display time zone, then convert.
Unix 0 is 1970-01-01T00:00:00.000Z.
An explicit input offset identifies one instant. The selected IANA zone determines its display, including daylight-saving rules.
