In what scenarios would omitting the timestamp parameter in date() function calls be advantageous in PHP scripts?

Omitting the timestamp parameter in date() function calls can be advantageous when you want to get the current date and time instead of a specific date and time. This can be useful for displaying the current date and time on a webpage, logging events with the current timestamp, or any other scenario where the current date and time is needed.

$currentDateTime = date('Y-m-d H:i:s');
echo $currentDateTime;
