Common mistake: mixing up seconds and milliseconds
The single most frequent timestamp bug is a unit mismatch. JavaScript's Date.now() returns milliseconds, while most server-side languages and APIs return seconds. Pass 1767225600000 where seconds are expected and the resulting date lands roughly 56,000 years in the future; pass 1767225600 where milliseconds are expected and you get 1970-01-21 10:53:45 UTC. The fix: after pasting a value above, read the status line under the timestamp field. This tool prints "Detected seconds" or "Detected milliseconds" on every conversion, so you always know which unit your number was interpreted as before you trust the result.
Which unit does your language use?
| Language | Function | Unit returned |
|---|
| JavaScript | Date.now() | Milliseconds |
| Python | time.time() | Seconds (float) |
| Java | System.currentTimeMillis() | Milliseconds |
| Go | time.Now().Unix() | Seconds |
| PHP | time() | Seconds |
| Unix shell | date +%s | Seconds |
Pro tip: dates before 1970
The timestamp field also accepts negative values, which represent moments before the Unix epoch. For example, -1 converts to 1969-12-31 23:59:59 UTC and -86400 is 1969-12-31 00:00:00 UTC. Useful when working with historical records or testing boundary conditions in date-handling code.
