Timestamp Converter
Convert between Unix timestamps and dates
The timestamp converter translates between Unix timestamps (Epoch time) and human-readable date-time formats. It supports both seconds and milliseconds precision, and outputs results in UTC, ISO 8601, and local time. Whether you are debugging API responses, inspecting server logs, or generating test dates, this developer-focused tool makes timestamp conversions fast and effortless.
๐ How to Use
- Enter a timestamp or date
- Select seconds or milliseconds unit
- Conversion results appear automatically
- Click 'Now' button to get current time
โจ Features

๐ก Use Cases
- โขBackend Developers: Convert Unix timestamps in API responses or databases to readable dates for debugging.
- โขDevOps Engineers: Translate Epoch timestamps in server logs to local time to pinpoint when events occurred.
- โขFront-End Developers: Convert JavaScript Date.now() millisecond values to formatted dates during debugging.
- โขData Analysts: Transform timestamp columns in datasets into human-readable dates for reporting.
- โขQA Engineers: Generate specific timestamps for test scenarios that validate time-dependent features.
๐ฏ Tips
- โธClick the Now button to instantly see the current timestamp in both seconds and milliseconds.
- โธA 10-digit number is seconds, a 13-digit number is milliseconds โ use this to choose the right mode.
- โธISO 8601 format (e.g., 2024-01-15T09:30:00Z) is the recommended standard for API design.
- โธNegative timestamps represent dates before January 1, 1970.
โ FAQ
Q. What is a Unix timestamp?
A. It's the number of seconds (or milliseconds) elapsed since January 1, 1970 00:00:00 UTC.
Q. Is it the same as JavaScript's Date.now()?
A. Date.now() returns milliseconds. Select the milliseconds option in this tool for the same value.
Q. What is the Year 2038 problem?
A. On 32-bit systems, the maximum representable Unix timestamp (2,147,483,647) corresponds to January 19, 2038. 64-bit systems do not have this limitation.
Q. Does the timestamp include timezone information?
A. A Unix timestamp is always relative to UTC. When displayed as local time, your browser timezone is applied automatically.
Q. How do I tell if a timestamp is in seconds or milliseconds?
A. As of recent years, a seconds timestamp is roughly a 10-digit number (around 1.7 billion), while a milliseconds timestamp is a 13-digit number (around 1.7 trillion).
