How can PHP functions like time and date be utilized effectively in a login system for time tracking purposes?

To utilize PHP functions like time and date effectively in a login system for time tracking purposes, you can store the login time in a database along with the user's ID. When the user logs out, you can calculate the total time they spent logged in by subtracting the login time from the current time. This can help track user activity and monitor login durations. 

// Store login time in database
$login_time = time();
$user_id = 123; // User's ID
// Save $login_time and $user_id in database

// Calculate total login duration when user logs out
$current_time = time();
$total_login_duration = $current_time - $login_time;
// Save $total_login_duration in database or use it for tracking purposes
