Current Time

Quick Start Guide

1📝 Timestamp to Date

  1. Paste your timestamp in the left input box below
  2. Tool automatically detects seconds/milliseconds format
  3. Instantly view conversion results in multiple formats
  4. Click "Copy" buttons to get results to clipboard
Example: Input 1640995200 → 2022-01-01 00:00:00

2📅 Date to Timestamp

  1. Select date and time in the right panel below
  2. Adjust timezone settings as needed
  3. View the generated timestamp results
  4. Copy desired format to clipboard
Tip: Timezone only affects display, not timestamp value

Display Settings

💡 Important: Timezone settings only affect time display format, not the timestamp value itself. The same timestamp shows different times in different timezones, but represents the same moment in time.

Professional Timestamp Converter Guide

About This Tool

This timestamp converter is developed by the HandyTool.top team, specifically designed for developers and technical professionals. We have over 5 years of web development experience and deeply understand the importance and complexity of time handling in software development. The tool is built on JavaScript's native Date API, ensuring accuracy and reliability of conversion results.

What is a Timestamp?

A timestamp is a standard way to represent time in computer systems, indicating the total number of seconds or milliseconds from January 1, 1970, 00:00:00 UTC (Unix epoch) to a specific time point. This representation avoids timezone complexity and is a universal standard for cross-platform time processing.

Technical Details: Unix timestamps are based on the IEEE Std 1003.1 standard, ensuring consistency across operating systems.

Supported Precision & Formats

  • Second Timestamps: 10-digit numbers, suitable for most applications
  • Millisecond Timestamps: 13-digit numbers, providing higher precision
  • ISO 8601: International Organization for Standardization time format
  • Multi-timezone Support: Accurate handling of global timezones

Real-world Applications

  • Web Development: API endpoint time parameter handling
  • Database Design: Time field storage and querying
  • Log Analysis: Server log timestamp parsing
  • Data Migration: Cross-system time format conversion
  • Performance Monitoring: Event time recording and analysis
  • Internationalization: Multi-timezone time display

Pro Tip: The tool uses intelligent detection algorithms to automatically identify input timestamp types, reducing manual selection errors.

Technical Implementation Principles

Core Algorithm: Based on JavaScript's native Date object and Intl.DateTimeFormat API

Timezone Handling: Uses IANA timezone database, ensuring timezone conversion accuracy

Precision Guarantee: Millisecond-level calculation precision for high-precision time requirements

Real-time Updates: Current time automatically refreshes every second, maintaining data timeliness

Intelligent Detection: Automatic timestamp type detection based on numerical ranges (seconds/milliseconds)

Why Use This Tool

Solving Real Problems: In daily development work, we often need to convert between Unix timestamps and human-readable date formats. Traditional online tools often have limited functionality, insufficient precision, or complex interfaces.

Improving Development Efficiency: This tool is specifically designed for developers, providing instant conversion, multi-format support, intelligent detection, and other features that significantly improve time processing work efficiency.

Ensuring Data Accuracy: Based on standard time processing algorithms, ensuring conversion result accuracy and avoiding errors that may occur with manual calculations.

Completely Free to Use: We believe excellent tools should be used by more people, so we provide it completely free, no registration required, ready to use.
