    console.log('Usage: loadpage.js <some URL>');
    phantom.exit()
}
t = Date.now();
address = system.args[1];
page.open(address, function (status) {
    if (status !== 'success') {
        console.log('Unable to load the address!');
        
    } else {
        t = Date.now() - t;
        console.log('Loading '+ system.args[1]);
        console.log('Loading time ' + t + ' msec');
    }
    phantom.exit();
});
