How can PHP users accurately determine the current time in a specific timezone to prevent manipulation by users?

To accurately determine the current time in a specific timezone and prevent manipulation by users, PHP users can use the DateTime class along with the setTimeZone() method to set the desired timezone. This ensures that the time displayed is based on the specified timezone regardless of the user's system settings.

// Set the desired timezone
$timezone = new DateTimeZone('America/New_York');
$date = new DateTime('now', $timezone);

// Display the current time in the specified timezone
echo $date->format('Y-m-d H:i:s');
