How it works
A Unix timestamp is the number of seconds (or milliseconds, depending on the system) since January 1st, 1970 at midnight UTC (the "Unix epoch") — the most common date format in databases, APIs, and system logs. JavaScript uses milliseconds internally; many APIs and databases (like PostgreSQL, MySQL) use seconds. When converting a timestamp to a date, we show both UTC time and your browser's local time, since the difference between the two is usually the biggest source of confusion when debugging date issues.
