About Unix Timestamp Converter
Convert any Unix timestamp (epoch seconds or milliseconds) to a readable UTC and local date-time string. Or pick a date and time and convert it back to epoch. Shows both seconds and milliseconds. Useful for debugging logs, API timestamps, and database fields.
Use Cases
Decoding log timestamps, debugging API date fields, converting database epoch values, calculating time differences, checking token expiry times.
How It Works
Uses JavaScript's Date object to convert between Unix epoch and ISO-formatted date strings. Automatically detects whether the input is in seconds or milliseconds based on its magnitude.

What timezone does the output use?
Both UTC and your local browser timezone are shown side-by-side.
