What are the potential pitfalls of using PHP's time() function to calculate a countdown timer?

Using PHP's time() function to calculate a countdown timer can lead to inaccuracies due to the time it takes to execute the code. To solve this issue, you can store the initial timestamp when the countdown starts and calculate the remaining time based on the stored timestamp rather than continuously calling the time() function. 

// Store the initial timestamp when the countdown starts
$start_time = time();

// Calculate the remaining time based on the stored timestamp
$remaining_time = 60 - (time() - $start_time);

echo "Countdown: " . $remaining_time . " seconds remaining";
