API 타임스탬프를 읽기 쉬운 날짜로 변환하는 방법
원시 타임스탬프를 사람이 읽는 날짜 형식으로 안정적으로 변환하는 절차입니다.
API 응답은 종종 타임스탬프만 제공합니다. 단위와 시간대를 맞춰 변환하면 디버깅과 화면 표시가 쉬워집니다.
Start by confirming timestamp unit
Check if the value is in seconds or milliseconds before conversion.
Using the wrong unit creates meaningless dates.
Apply timezone intentionally
Readable output depends on timezone choice.
Decide whether you need UTC, server time, or user-local time.
Use one sample value to validate
Pick one timestamp with a known real-world time and compare conversion output.
This catches unit and timezone issues quickly.
- Confirm expected year.
- Check hour offset.
- Verify daylight saving periods if relevant.
Standardize display format
Use one consistent date format in your UI and logs.
Consistency reduces confusion across teams and locales.
When to use this
- Inspecting API responses.
- Building dashboards.
- Formatting logs.
- Showing dates in admin tools.
Convert with context
Always convert with the correct unit and timezone, then validate one known sample value.
