What is a Unix Timestamp?
A Unix timestamp (also known as Epoch time or POSIX time) represents the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC.
In Blockchain
Every block and transaction on most blockchains includes a Unix timestamp, making it essential for verifying when events occurred.

FAQ
- What is a Unix timestamp?
- A Unix timestamp (epoch time) is the number of seconds—or sometimes milliseconds—that have elapsed since 00:00:00 UTC on 1 January 1970. It is a compact, timezone-independent way to store and compare moments in time.
- How do I convert a Unix timestamp to a date?
- Paste the epoch value into the converter, choose seconds or milliseconds if needed, and read the human-readable UTC (and local) date. Most blockchain APIs return seconds; JavaScript Date often uses milliseconds.
- Seconds vs milliseconds — which should I use?
- Classic Unix time uses seconds (about 10 digits today). Milliseconds are common in JavaScript and some APIs (13 digits). If a value looks ~1000× too large or small, you likely picked the wrong unit.
- Why do blockchain developers need Unix timestamps?
- Blocks, transactions, and on-chain events almost always include an epoch time. Converting those values helps you debug explorers, verify confirmations, and align off-chain logs with chain data.
