All conversions happen locally in your browser using JavaScript. Your timestamps never leave your device, ensuring complete privacy. No server uploads, no tracking beyond basic analytics—just pure client-side processing.
🌐 Auto-Detection & Multiple Formats
Automatically detects seconds (10 digits) vs milliseconds (13 digits). Displays results in ISO 8601, RFC 2822, SQL datetime, and custom formats. Unlike basic converters, Filator handles all timestamp variations intelligently.
♾️ Batch Conversion & Live Clock
Convert multiple timestamps at once instead of one-by-one. Live Unix clock shows current epoch time with real-time updates. Batch features save hours when debugging logs or migrating data.
How to Convert Unix Timestamp to Date Step-by-Step
- 1.Enter your Unix timestamp in seconds (10 digits, e.g., 1710498600) or milliseconds (13 digits, e.g., 1710498600000)
- 2.The tool auto-detects the format and instantly displays the human-readable date in multiple formats (ISO 8601, RFC 2822, SQL datetime)
- 3.Select your preferred timezone (UTC, EST, PST, etc.) to see the local time conversion
- 4.Copy the result with one click or convert from date to Unix timestamp using the reverse mode

What is Unix Timestamp (Epoch Time)?
Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC, not counting leap seconds. It's a standard way to represent time in computing systems because it's timezone-independent and easy to work with mathematically. The format is used universally in databases (MySQL, PostgreSQL), programming languages (JavaScript, Python, PHP), APIs, and log files.
Advanced Features

Frequently Asked Questions
How do I convert Unix timestamp to date online?
Enter your Unix timestamp (in seconds or milliseconds) into the converter field and it instantly shows the human-readable date. Our tool auto-detects whether you're using seconds (10 digits) or milliseconds (13 digits) and converts accordingly. All processing happens in your browser with no server uploads.
What is Unix timestamp (epoch time)?
Unix timestamp (also called epoch time or POSIX time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It's a standard way to track time in computing systems and is used by databases, APIs, and programming languages worldwide.
What's the difference between Unix seconds and milliseconds?
Unix timestamp in seconds is the standard format (10 digits for current dates), while milliseconds (13 digits) provides more precision. JavaScript, Node.js, and many modern systems use milliseconds. To convert: milliseconds = seconds × 1000. Our tool handles both formats automatically.
Are Unix timestamps timezone dependent?
No, Unix timestamps are always in UTC (Coordinated Universal Time). They represent the same moment in time regardless of timezone. Timezone conversion only happens when displaying the timestamp as a human-readable date. This is why Unix timestamps are perfect for storing time in databases.
How do I get current Unix timestamp?
In JavaScript: Math.floor(Date.now()/1000) for seconds or Date.now() for milliseconds. In Python: import time; time.time(). In PHP: time(). In Java: System.currentTimeMillis()/1000. Our tool shows the live current Unix timestamp at the top with real-time updates.
When will Unix timestamp overflow (Year 2038 problem)?
The 32-bit Unix timestamp will overflow on January 19, 2038 at 03:14:07 UTC (reaching 2,147,483,647 seconds). However, modern 64-bit systems are not affected and can represent dates billions of years into the future. Most systems have already migrated to 64-bit timestamps.
Can I convert multiple timestamps at once?
Yes! Our batch conversion feature lets you convert multiple Unix timestamps simultaneously. Simply paste a list of timestamps and get instant results for all of them. Unlike epochconverter.com and unixtimestamp.com which require separate conversions, Filator processes them all at once.
Is the Unix timestamp converter free to use?
Yes, completely free with no limitations. Unlike some converters with ads (epochconverter.com, unixtimestamp.com), Filator is ad-free. No signup required, no premium upsells, unlimited conversions. All processing is client-side in your browser for complete privacy.
