Preguntas frecuentes
- Does the tool auto-detect seconds vs milliseconds?
- Yes. A 10-digit value is treated as seconds and a 13-digit value as milliseconds. Values below 1e12 are multiplied by 1000.
- Can I convert a date string to a timestamp?
- Yes. Paste any date string parseable by JavaScript (ISO 8601, RFC 2822, etc.) and the tool returns the Unix timestamp.
- What output formats are shown?
- The tool displays Unix timestamp in both seconds and milliseconds, plus the UTC (ISO 8601) and local time representations.
- What is the Unix epoch?
- The Unix epoch is 1970-01-01T00:00:00Z. Unix timestamps count seconds (or milliseconds) from this reference point. Negative values represent dates before 1970.
- Why does my date string parse differently across browsers?
- Non-ISO date strings (e.g. '01/15/2023') are parsed according to local timezone and may vary by browser. ISO 8601 strings (e.g. '2023-01-15T10:30:00Z') are parsed consistently.
- Is the 2038 problem relevant?
- JavaScript Date supports up to ±8.64e15 milliseconds (year 275760), so 32-bit signed integer overflow (Jan 19, 2038) does not apply. Legacy C programs may still be affected.
