🕒 Real-Time Clock Partition Simulator

A dynamic, interactive web-based simulation of real-time clock (RTC) management and synchronization across OS partitions.
Built for Linux session.

---

🚀 Overview

This project demonstrates master-slave RTC synchronization in a multi-partition system:

• Linux acts as the Master Partition, reading time from the hardware clock.
• Windows OS and Ubuntu are Slave Partitions whose clocks can drift and become out of sync.
• You can simulate clock drift, observe out-of-sync states, and manually synchronize all partitions—just like using timedatectl set-local-rtc 1 in Linux.

---

✨ Features

• Live RTC Simulation: Visualize how clocks drift and sync in real time.
• Master-Slave Architecture: Linux (master) always stays in sync; others can drift.
• Manual & Bulk Sync: Instantly synchronize all slave partitions with a single click.
• Visual Feedback: Out-of-sync states are clearly highlighted.
• Modern UI: Responsive, attractive interface using React and Next.js.
• Command Simulation: Simulate Linux RTC commands and observe their effects.

🛠️ Getting Started

1. Clone the repository

git clone https://github.com/yourusername/linux-proj.git
cd linux-proj

2. Start the RTC Master Server

cd rtc-sim
npm install
node index.js

3. Start the Frontend

cd ../frontend
npm install
npm run dev

Open http://localhost:3000 in your browser.

⚙️ How It Works

• Master Clock: The backend (rtc-sim/index.js) broadcasts the current time to all partitions.
• Partitions: Each partition (component) simulates its own clock, which may drift.
• Synchronization: Slave partitions periodically sync to the master, or can be manually synced via UI buttons.
• Command Simulation: Use the UI to simulate commands like timedatectl set-local-rtc 1 for instant synchronization.

🖥️ Useful Commands

The following commands (from Commands.txt) are useful for working with the kernel RTC module:

make

sudo insmod rtc_sync.ko

sudo dmesg | grep rtc_shm

ls -l /dev/rtc_shm

cat /dev/rtc_shm

gcc rtc_slave.c -o rtc_slave

sudo ./rtc_slave

sudo rmmod rtc_sync
