What are the advantages of storing timestamps instead of full date and time values in PHP?

Storing timestamps instead of full date and time values in PHP can be advantageous because timestamps are more compact and efficient to store and manipulate. They also provide a standardized way to represent time, making it easier to perform calculations and comparisons. Additionally, timestamps are timezone-independent, which can simplify handling date and time values across different timezones. 

// Storing a timestamp in PHP
$timestamp = time();

// Retrieving the current date and time from a timestamp
$date = date('Y-m-d H:i:s', $timestamp);

// Converting a timestamp to a different timezone
$timezone = new DateTimeZone('America/New_York');
$date = new DateTime();
$date->setTimestamp($timestamp);
$date->setTimezone($timezone);
echo $date->format('Y-m-d H:i:s');
