Use a unix timestamp converter for logs and APIs
A unix timestamp converter turns the long numbers in logs into dates you can read. Paste a value and see local time, UTC, and ISO in one place.
Go the other way when you write scripts or API calls. Type a date and copy seconds or milliseconds without opening a spreadsheet.
This unix timestamp converter runs in your browser, so you can debug on a shared machine without uploading timestamps.
Good for
- Log debugging
- API payloads
- Script timestamps
- Epoch checks
Tips
- Check seconds vs milliseconds
- Compare local and UTC
- Copy the ISO string for APIs
- Paste one value at a time
