常見問題
03
Does it support both 10-digit and 13-digit values?
Yes. The tool auto-detects precision: 10-digit numbers are interpreted as Unix seconds (the C and Python convention), and 13-digit numbers as milliseconds (the JavaScript convention). Values outside those lengths are flagged as out of range. If a valid-looking number gives an unexpected date, check whether the source system uses seconds, milliseconds, or microseconds — there is no universal standard across languages and platforms.
What time zone is used for local time output?
Your browser's local system time zone is used for the local time display.
Can I convert a date string back to a Unix timestamp?
Yes. ISO 8601 strings like 2024-01-15T10:30:00Z are accepted and converted to epoch values.
