What are the potential challenges faced when trying to display date and time on webcam images using PHP and FTP servers?

One potential challenge faced when trying to display date and time on webcam images using PHP and FTP servers is ensuring that the date and time displayed are accurate and synchronized with the server's time. This can be achieved by retrieving the server's current date and time and embedding it onto the images before uploading them via FTP. 

<?php
// Get the current date and time from the server
$currentDateTime = date('Y-m-d H:i:s');

// Embed the date and time onto the image
$image = imagecreatefromjpeg('webcam_image.jpg');
$fontColor = imagecolorallocate($image, 255, 255, 255);
imagettftext($image, 10, 0, 10, 20, $fontColor, 'arial.ttf', $currentDateTime);

// Save the modified image
imagejpeg($image, 'webcam_image_with_datetime.jpg');

// Upload the image to FTP server
$ftpConnection = ftp_connect('ftp.example.com');
ftp_login($ftpConnection, 'username', 'password');
ftp_put($ftpConnection, '/public_html/webcam_image_with_datetime.jpg', 'webcam_image_with_datetime.jpg', FTP_BINARY);
ftp_close($ftpConnection);

// Display success message
echo 'Image uploaded with date and time successfully.';
?>
