Understanding Timestamps & Unix Epoch
What is a Unix Timestamp?
A Unix timestamp (also called epoch time or POSIX time) is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970. Our free online timestamp converter makes it easy to convert between timestamps and human-readable dates.
// Unix timestamp in seconds 1704067200 → January 1, 2024 00:00:00 UTC // Unix timestamp in milliseconds 1704067200000 → January 1, 2024 00:00:00 UTC // Common date formats ISO 8601: 2024-01-01T00:00:00Z RFC 2822: Mon, 01 Jan 2024 00:00:00 GMT US Format: 01/01/2024 12:00:00 AM European Format: 01/01/2024 00:00:00
Seconds vs Milliseconds Timestamps
Understanding the difference between seconds and milliseconds timestamps:
- Seconds Timestamps: 10 digits, counts seconds since epoch (e.g., 1704067200)
- Milliseconds Timestamps: 13 digits, counts milliseconds since epoch (e.g., 1704067200000)
- Conversion: Milliseconds = Seconds × 1000
- Year 2038 Problem: 32-bit seconds timestamps will overflow on January 19, 2038

Timestamp Converter FAQ - Common Questions
Is my timestamp data secure and private?
Yes! Our free online timestamp converter processes all conversions entirely in your browser. Your data never leaves your device, ensuring complete privacy and security. We don't store, transmit, or have access to any of your data.
What's the difference between Unix timestamp in seconds and milliseconds?
Unix timestamp in seconds counts the number of seconds since January 1, 1970 (Unix epoch).Milliseconds timestamps count the number of milliseconds since the same epoch. Seconds timestamps are typically 10 digits (up to year 2038), while milliseconds timestamps are 13 digits.
Can I convert timestamps to different timezones?
Yes! Our timestamp converter supports timezone conversion. You can convert timestamps to UTC, your local timezone, or any major timezone worldwide including America/New_York, Europe/London, Asia/Tokyo, and more.
Does the tool handle negative timestamps (dates before 1970)?
Yes! Our timestamp converter online handles both positive and negative timestamps, allowing you to convert dates before January 1, 1970 (Unix epoch). This is useful for historical dates.
Which date formats are supported for input?
Our timestamp converter automatically detects and supports ISO 8601 (2024-01-01T00:00:00Z), RFC 2822 (Mon, 01 Jan 2024 00:00:00 GMT), US format (01/01/2024), European format (01/01/2024), and most common date string formats.
Is the timestamp converter completely free to use?
Yes! Our free timestamp converter is completely free with no registration required, no hidden costs, and no usage limits. You can convert unlimited timestamps, download results, and use all features without any restrictions.
