Epoch / Unix Timestamp Converter

Unix epoch time (also called POSIX time or "epoch seconds") counts the number of seconds that have elapsed since 1970-01-01 00:00:00 UTC, ignoring leap seconds. It is the most common way to represent timestamps in databases, log files, file systems, network protocols, and APIs because it is timezone-free, sortable, and easy to compare.

This converter handles seconds, milliseconds, microseconds and nanoseconds so you can decode timestamps from any source — Postgres, Linux stat, JavaScript Date.now(), Kafka message timestamps, and the exp/iatclaims in a JWT — into a human-readable date and time, in either UTC or your local timezone.

1. Paste an integer timestamp into the input. The tool auto-detects whether it is seconds, milliseconds, microseconds or nanoseconds based on the magnitude.
2. Read the human-readable result in both UTC and your local timezone.
3. Use the reverse direction to convert a date-time back to epoch in any of the supported precisions.
4. Copy the value you need with one click.

• Reading timestamps in raw log files or audit trails.
• Building time-bounded queries against a Postgres table that stores Unix timestamps.
• Debugging cache expirations and JWT exp claims.
• Cross-referencing events across services that use different time units.
