What potential pitfalls should be considered when using cron jobs in PHP for time-based operations?

One potential pitfall when using cron jobs in PHP for time-based operations is not handling errors or exceptions properly, which can lead to unexpected behavior or downtime. To mitigate this risk, it's important to implement error handling in your PHP scripts that are executed by cron jobs. 

// Example of implementing error handling in a PHP script executed by a cron job
try {
    // Your time-based operations code here
} catch (Exception $e) {
    // Log the error to a file or send an email notification
    file_put_contents('cron_errors.log', '[' . date('Y-m-d H:i:s') . '] ' . $e->getMessage() . PHP_EOL, FILE_APPEND);
}
