자주 묻는 질문
Why are some timestamps 13 digits and others 10?+
10 digits = seconds since 1970-01-01 UTC. 13 digits = milliseconds. The tool detects both automatically based on length.
Does it handle leap seconds?+
No. Unix time intentionally ignores leap seconds — they are smeared at the OS level. This converter follows the same convention as every standard library.
What timezone is shown?+
ISO 8601 output is always UTC. The "Local" line uses your browser locale and timezone via Intl.DateTimeFormat.
