두 날짜 사이의 기간을 계산합니다.
Unix 타임스탬프와 날짜를 상호 변환합니다.
자세한 방법과 예시는 영어로 제공됩니다.
Unix time measures seconds since 1 January 1970 at 00:00:00 UTC. Millisecond input is divided by 1,000 for Unix seconds, with fractional seconds rounded down. Date-to-timestamp input is explicitly interpreted as UTC.
Unix timestamp 0 is 1 January 1970 at 00:00:00 UTC. The equivalent millisecond value is also 0.
Inspect application logs, API timestamps, or stored event dates without doing epoch arithmetic manually. Matching the unit used by the source system is essential before comparing two event times.
The most common cause is using milliseconds as seconds or the reverse. Check the explicit unit selector and the source API documentation.
It represents January 1, 1970 at 00:00:00 UTC. A displayed local date can differ if another application applies a time-zone offset.
