Unix Timestamp
Convert between timestamps and readable date values. Free online developer tool for fast browser-based work.
What is this tool?
Unix Timestamp converts between epoch values and readable dates so logs, APIs and database records are easier to troubleshoot across systems.
How to use
- Paste a Unix timestamp or choose a readable date and time.
- Convert in the direction that matches your log, API or database field.
- Compare the result with timezone expectations before using it in a bug report.
Practical example
Timestamps make logs compact, but readable dates make incidents easier to discuss.
Unix seconds: 1893456000
Readable UTC: 2030-01-01 00:00:00
Check whether your system uses seconds or milliseconds.API
Use date and timestamp utilities with API examples when testing time-based behavior.

Frequently asked questions
What is a Unix timestamp?
It is a numeric count of time since 1970-01-01 UTC, commonly represented in seconds or milliseconds.
Why is my converted date far in the future?
You may be treating milliseconds as seconds or seconds as milliseconds.
Should I compare timestamps in local time?
Use UTC for technical comparisons, then convert to local time only for presentation.
Limitations / when not to use
The biggest timestamp mistake is mixing seconds and milliseconds. Always confirm the unit and timezone used by the source system.
