Epoch (Unix Timestamp) Converter

Workflow & Usage

1. Paste or type your input into the left textarea.
2. Use the Epoch / Date toggle inside the input area to switch modes.
3. Choose:
   • Seconds or milliseconds
   • UTC or local time
4. Optional controls:
   • Batch by newline — convert one value per line
   • Trim lines — ignore leading and trailing whitespace
5. View the result instantly on the right and copy with one click.

Invalid values are reported per line, so one error won’t affect the rest of the batch.

Common Use Cases

• Debugging API responses
• Inspecting logs and analytics data
• Working with JWT expiration times (iat, exp)
• Database timestamps
• Comparing or sorting events by time
• Converting human input to machine-friendly values

---

Tips & Best Practices

• Always verify whether a timestamp is in seconds or milliseconds.
• Use UTC when working with APIs, logs, or distributed systems.
• Use local time when validating user-facing dates.
• Batch mode is ideal for cleaning up or inspecting large datasets.

How It Works

• Epoch values are interpreted as numeric timestamps
• Date strings are parsed using the browser’s Date engine
• Timestamps are converted using standard JavaScript time APIs
• Each line is processed independently
• All logic runs locally, in real time
