What is Unix Timestamp Converter?
Unix Timestamp Converter helps you convert epoch time to a readable date and convert a date back to a Unix timestamp. Unix time is the number of seconds (or milliseconds) since January 1, 1970 (UTC) and shows up everywhere: server logs, database fields, API responses, analytics events, job schedulers, and JWT expiration claims. This tool auto-detects 10-digit timestamps (seconds) vs 13-digit timestamps (milliseconds), displays the result in UTC and local time, and makes it easy to avoid common timezone mistakes when debugging production systems.
How to Use
1
Paste a Unix timestamp (seconds or milliseconds) into the input
2
Or paste a date/time string (ISO 8601, common formats, or readable dates)
3
Click Convert to generate the result instantly
4
Review UTC and local timezone output to confirm the expected time
5
Copy the converted timestamp or formatted date for logs, APIs, or code
Common Use Cases
Convert timestamps from server logs into readable incident timelines
Verify API event times by converting timestamp fields to dates
Convert database epoch columns into human-readable values for debugging
Fix timezone bugs by comparing UTC output with local time output
Create timestamps for cron jobs, schedules, and delayed execution
Check JWT exp/iat/nbf timestamps when debugging authentication
