What is the Timestamp Converter?

Translate Unix Epoch timestamps into human-readable date formats (UTC, ISO 8601, and local browser time) and vice versa. It features an active live clock showing the current Unix second, auto-detects 10-digit second and 13-digit millisecond timestamps, and provides a date-time picker to generate epoch integers.

How to Use This Tool

  1. To convert a timestamp: paste the numeric integer into the "Epoch Seconds" input.
  2. View formatted UTC time, Local system time, and ISO 8601 strings.
  3. To convert a date into an Epoch integer: select a date and time in the right panel.
  4. Click "Use Current Time" to instantly load the current epoch second.

Examples & Use Cases

Historic Epoch Milestone

Input: Timestamp: 1700000000
Result: Wednesday, November 15, 2023 22:13:20 UTC (ISO: 2023-11-15T22:13:20.000Z)

Formula & Technical Specifications

Unix epoch time counts seconds elapsed since 00:00:00 UTC on January 1, 1970 (excluding leap seconds). Supports 64-bit timestamps far past the 2038 Year problem.

Limitations, Edge Cases & Best Practices

Timestamps before 1970 are represented by negative integers. Our converter accurately handles negative integers back to the beginning of modern calendar records.

Privacy & Client-Side Execution

All date conversions occur locally on your machine.

Frequently Asked Questions

What is the difference between 10-digit and 13-digit timestamps?

10-digit timestamps measure elapsed time in seconds (standard in PHP, Python, and C). 13-digit timestamps measure elapsed time in milliseconds (standard in JavaScript Date.now()). Our tool auto-detects both.
