Unix Timestamp Converter

Convert numeric Unix epoch timestamps (seconds or milliseconds) into human-readable dates (UTC and local time), and convert human dates back into Unix timestamps.

Why Use This Converter?

• Backend Debugging: Inspect timestamp numbers from database columns (e.g., `created_at = 1787063400`).
• API Development: Convert user input dates into Unix epoch seconds for API request payloads.
• Log Investigation: Determine the exact human date and time of server log events.

How to Use

1. Enter a Unix timestamp (10 or 13 digits) or select a date/time from the picker.
2. View automatic conversion to ISO 8601, UTC string, Local Time, and relative time ("2 hours ago").
3. Click copy to copy any formatted value.
