What are the potential drawbacks of using a cron job to check for time-based events in a PHP application?

One potential drawback of using a cron job to check for time-based events in a PHP application is that it adds complexity and requires additional server configuration. A more efficient solution would be to use PHP's built-in date and time functions to check for time-based events within the application itself, eliminating the need for external cron jobs. 

// Example of checking for a time-based event within a PHP application
$current_time = time();
$event_time = strtotime('2022-01-01 00:00:00');

if ($current_time >= $event_time) {
    // Time-based event has been reached, execute necessary code
    // For example: send an email, update a database record, etc.
}
