About Timestamp Converter
Free online Unix timestamp converter. Convert epoch timestamps to human-readable dates and times, or convert any date to its Unix timestamp. Live current timestamp display. Supports seconds and milliseconds. Essential for debugging APIs and databases.
The live current timestamp display makes it perfect for quick reference — bookmark this page and it always shows the current time in Unix format. Converts between seconds and milliseconds automatically, and shows timestamps in 3 human-readable formats simultaneously.
How to Use Timestamp Converter
- 1The current Unix timestamp is shown live at the top, updating every second.
- 2To convert a timestamp to a date: paste any Unix timestamp (seconds or milliseconds) into the input and see the UTC, ISO 8601, and local date immediately.
- 3To convert a date to a timestamp: use the datetime picker to select any date and time.
- 4Copy any format with the copy button — seconds, milliseconds, UTC string, ISO 8601, or local.
- 5The tool automatically detects whether your input is seconds (10 digits) or milliseconds (13 digits).
Key Features
Use Cases for Timestamp Converter
API Debugging
REST APIs frequently use Unix timestamps for created_at, updated_at, and expires_at fields. Convert these timestamps instantly to understand when events occurred without mental math.
Database Record Investigation
SQL databases often store dates as Unix timestamps. Convert database timestamps to readable dates when debugging data issues, investigating user behavior, or verifying import correctness.
JWT Token Expiry
JWT tokens contain exp (expiration) and iat (issued at) Unix timestamps in the payload. Convert these values to verify tokens are expiring at the correct time and haven't already expired.
Log Timestamp Analysis
Many log systems record events as Unix milliseconds. Convert log timestamps to understand the exact sequence of events and how much time elapsed between them.
JavaScript's Date.now() returns milliseconds (13 digits). Most Unix timestamp fields in databases and APIs use seconds (10 digits). If your timestamp looks like 1700000000000 (13 digits), divide by 1000 to get seconds. Our converter detects this automatically.
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp is the number of seconds elapsed since January 1, 1970 00:00:00 UTC (the Unix epoch). It's the universal time format in software systems.
What is the current Unix timestamp?
The current Unix timestamp is shown live above. You can also get it in JavaScript with Date.now() (milliseconds) or Math.floor(Date.now()/1000) (seconds).
