Timestamp Converter은(는) 무엇을 하나요?
Timestamp Converter은(는) 브라우저에서 데이터 또는 파일 변환을(를) 수행하며 결과와 제한을 명확히 설명합니다. 검증된 기능: Seconds through nanoseconds, UTC ISO 8601, IANA time zones, Date-to-epoch conversion.
Store instants; choose zones for display
Use Unix time or offset-bearing ISO 8601 for an instant. Apply an IANA time zone only when presenting that instant as a regional wall time.
사용 방법
- Paste a timestamp and keep Auto-detect or choose its exact unit.
- Select the time zone used for the readable display.
- Copy the ISO 8601, Unix-second, or millisecond value required by the target system.

1970-01-01T00:00:00.000ZUnix time zero is the UTC epoch; local displays apply their zone offset to the same instant.
일반적인 오류와 해결 방법
| 현상 | 가능한 원인 | 해결 방법 |
|---|---|---|
| The year is far in the future. | A millisecond value was interpreted as seconds. | Choose Milliseconds or use Auto-detect on the complete value. |
| The displayed hour differs between systems. | The systems use different time zones or one input lacks an offset. | Compare ISO 8601 UTC output and specify the intended IANA zone. |
Unit and zone assumptions change the display
이 도구의 구체적인 제한: Treating milliseconds as seconds creates a date far outside the expected year. A local date can also shift when one system assumes UTC and another omits the offset.

Timestamp Converter — FAQ
How are units detected?
Up to 10 digits is seconds, up to 13 milliseconds, up to 16 microseconds, and longer values nanoseconds.
Does time zone change a timestamp?
No. It changes only the displayed local representation of the same instant.
Is daylight saving time included?
Yes when the browser has current IANA time-zone data.
변경 사항
실질적인 업데이트: Timestamp Converter: Added automatic unit detection, bidirectional conversion, ISO 8601 output, selected IANA zones, and relative time.
