🎯 Use Cases

1. Software Development

Handling timestamps in software development:

// Get current timestamp in JavaScript
const timestamp = Math.floor(Date.now() / 1000); // seconds
const timestampMs = Date.now(); // milliseconds

// Convert timestamp to date
const date = new Date(timestamp * 1000);

2. Database Operations

Handling timestamp fields in databases:

-- Timestamp conversion in MySQL
SELECT FROM_UNIXTIME(1640995200) AS datetime;
SELECT UNIX_TIMESTAMP('2024-01-01 12:00:00') AS timestamp;

3. Log Analysis

Analyzing timestamps in server logs:

# Timestamp conversion in Linux systems
date -d @1640995200
date +%s -d "2024-01-01 12:00:00"

4. API Development

Handling timestamps in API responses:

{
  "created_at": 1640995200,
  "updated_at": "2024-01-01T12:00:00Z",
  "timestamp": 1640995200000
}

🌍 Timezone Support

📚 Common Timestamps

Important Time Points

• 0: Unix Epoch (January 1, 1970)
• 946684800: Y2K (January 1, 2000)
• 1000000000: Billionth second (September 9, 2001)
• 1234567890: Special timestamp (February 13, 2009)
• 1577836800: New Year 2020 (January 1, 2020)

Time Calculations

1 second = 1
1 minute = 60 seconds
1 hour = 3600 seconds
1 day = 86400 seconds
1 week = 604800 seconds
1 month (30 days) = 2592000 seconds
1 year (365 days) = 31536000 seconds

Timestamps in Programming Languages

JavaScript

// Get current timestamp
Date.now() // milliseconds
Math.floor(Date.now() / 1000) // seconds

// Convert timestamp
new Date(timestamp * 1000)

Python

import time
import datetime

# Get current timestamp
time.time() # seconds
