Need to find what time it was 12 hours ago?
Here are several ways to calculate it in different programming languages:
// PHP // Get time from 12 hours ago $pastDate = date('Y-m-d H:i:s', strtotime('-12 hours')); // Get time 12 hours from now $futureDate = date('Y-m-d H:i:s', strtotime('+12 hours')); // Using DateTime (recommended approach) $date = new DateTime(); $date->modify('-12 hours'); echo $date->format('Y-m-d H:i:s');
// JavaScript // Get time from 12 hours ago const pastDate = new Date(Date.now() - 12 * 60 * 60 * 1000); // Get time 12 hours from now const futureDate = new Date(Date.now() + 12 * 60 * 60 * 1000); // Alternative approach using date methods const date = new Date(); date.setHours(date.getHours() - 12); console.log(date.toISOString());
# Python from datetime import datetime, timedelta # Get time from 12 hours ago past_date = datetime.now() - timedelta(hours=12) # Get time 12 hours from now future_date = datetime.now() + timedelta(hours=12) # Format the dates print(past_date.strftime('%Y-%m-%d %H:%M:%S')) print(future_date.strftime('%Y-%m-%d %H:%M:%S'))
