Undefined reference to class methods using Code::Blocks

Coming from the Java/Eclipse world, just wanted to brush up on C++ and using Code::Blocks.

Was making a basic class and am having trouble implementing it to my main file.

Getting "undefined reference to 'Time::Time(int, int, int)'" and undefined reference errors to all of my methods used in my main.cpp file.

Tried rebuilding, tried re-adding the files to the console project. Not sure what the problem is. I'm fairly rusty with Code::Blocks so maybe it's something obvious, any help would be appreciated.

main.cpp

#include "Time.h"
#include <iostream>

using namespace std;

int main()
{
    //Time current();
    Time current(12,0,0);

    cout << "Current time." << endl;
    current.displayTime();

    cout << "\nSet time to 22:29:30." << endl;
    current.setTime(22,29,30);
    current.displayTime();

    cout << "\nAdd 45 minutes." << endl;
    current.addMinutes(45);
    current.displayTime();

    cout << "\nAdd 45 seconds." << endl;
    current.addSeconds(45);
    current.displayTime();

    cout << "\nAdd 1 hour." << endl;
    current.addHours(1);
    current.displayTime();

    return 0;
}

Time.h

#ifndef TIME_H

    public:
        Time(int h, int m, int s);
