Unix timestamp converter for logs, APIs and debugging

What is Timestamp Converter?

A Unix timestamp represents a date as the number of seconds or milliseconds elapsed since January 1, 1970 UTC.

Main use case: Convert timestamps from logs, API payloads, JWT claims or database records into readable dates.

Common use cases

Log analysis

Turn raw event times into readable dates.

API debugging

Check timestamp fields in JSON payloads.

Token inspection

Convert JWT exp and iat claims.

How to use the tool

1. Enter a date or timestamp.
2. Choose seconds or milliseconds.
3. Review the converted value.
4. Copy the output for your logs or API payload.

Best practices

• Use realistic test values when validating forms, exports or API payloads.
• Keep real customer, banking and production secrets out of public tools.
• Check the output format before copying it into a production workflow.
• Document whether a value is generated, validated, converted or only estimated.

Common mistakes

Confusing valid format with real-world validity

A generated or locally validated value can match a format without proving that it exists in an official system.

Using real production data

Public utilities are best for test data, demos, fixtures, QA and quick checks, not for confidential values.
