Code Implementation

Need to find what time it was 15 hours ago?
Here are several ways to calculate it in different programming languages:

// PHP
// Get time from 15 hours ago
$pastDate = date('Y-m-d H:i:s', strtotime('-15 hours'));

// Get time 15 hours from now
$futureDate = date('Y-m-d H:i:s', strtotime('+15 hours'));

// Using DateTime (recommended approach)
$date = new DateTime();
$date->modify('-15 hours');
echo $date->format('Y-m-d H:i:s');
// JavaScript
// Get time from 15 hours ago
const pastDate = new Date(Date.now() - 15 * 60 * 60 * 1000);

// Get time 15 hours from now
const futureDate = new Date(Date.now() + 15 * 60 * 60 * 1000);

// Alternative approach using date methods
const date = new Date();
date.setHours(date.getHours() - 15);
console.log(date.toISOString());
# Python
from datetime import datetime, timedelta

# Get time from 15 hours ago
past_date = datetime.now() - timedelta(hours=15)

# Get time 15 hours from now
future_date = datetime.now() + timedelta(hours=15)

# Format the dates
print(past_date.strftime('%Y-%m-%d %H:%M:%S'))
print(future_date.strftime('%Y-%m-%d %H:%M:%S'))
