Frequently asked questions
- What is a Unix timestamp?
- It's the number of seconds that have elapsed since 1970-01-01 00:00:00 UTC, known as the Unix epoch. Many systems store it in milliseconds instead, which is why the unit matters.
- How do I tell seconds from milliseconds?
- A millisecond timestamp is roughly 1,000× larger than the equivalent in seconds — a present-day value in seconds is about 10 digits, while milliseconds is about 13. Rather than guess, this tool asks you to pick the unit explicitly.
- Can it handle dates before 1970?
- Yes — timestamps before the epoch are negative, and they convert normally.
- Which time zone are the results in?
- Conversions are done in UTC, and the date-to-timestamp fields are interpreted as UTC. A Unix timestamp itself has no time zone; it's a fixed point in time.
