About This Tool
A Unix timestamp (also known as Epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds. It's the standard way computers track time across systems.
Live Current Timestamp: The real-time display at the top updates every second, showing the current Unix timestamp in seconds along with the UTC date. Use this for quick reference when debugging or logging.
Timestamp → Date: Enter a Unix timestamp in seconds (10 digits) or milliseconds (13 digits) and convert it to a human-readable UTC date, ISO 8601 format, and local time. This is useful for reading server logs, database timestamps, or API responses.
Date → Timestamp: Pick a date and time using the date picker and get the corresponding Unix timestamp in both seconds and milliseconds. The converter uses your local timezone and converts to UTC automatically.
Common Use Cases: Unix timestamps are used in databases (MySQL, PostgreSQL), programming languages (JavaScript Date, Python time, PHP time()), API design, log files, SSL certificates, JWT tokens, and file system metadata.
