About Unix timestamps
A Unix timestamp is the number of seconds since 00:00:00 UTC on 1 January 1970, the epoch. JavaScript, most databases, and many APIs store time as milliseconds since the same moment. A 10-digit number is almost always seconds; a 13-digit number is milliseconds. Timestamps do not carry timezone information — they are always the same absolute moment everywhere on Earth.
Use the Timestamp → Date box to paste a value from a log file, a database row, or an API response and see both the UTC instant and your local interpretation. Use the Date → Timestamp box to encode a specific moment in your local timezone back into epoch form — useful when filling in a `created_at` field manually or writing a test case. The current-timestamp card at the top updates every second if you just need to grab now.
Everything is computed in your browser with no server round trip. The conversion uses the built-in Date and Intl.DateTimeFormatAPIs, so the result follows whatever timezone database ships with your browser. If your system clock is wrong, the "current timestamp" will be wrong too — check your OS time settings before blaming the tool.
