Frequently Asked Questions about Timestamp Converter

Does it handle milliseconds automatically?

Yes. Timestamps over 10,000,000,000,000 (10 trillion) are automatically detected as milliseconds. Timestamps under this are treated as seconds (standard Unix epoch).

What date string formats are accepted?

Any format parseable by JavaScript's Date constructor: ISO 8601 (2024-01-15T09:00:00Z), RFC 2822, and most common formats like 'Jan 15, 2024' or '2024/01/15'.

Does the tool show UTC or local timezone?

Both. The tool displays the timestamp in UTC (Coordinated Universal Time) and in your browser's local timezone simultaneously. This is useful for debugging server logs recorded in UTC against your local time.
