What are the potential pitfalls of relying solely on client-side JavaScript for time zone conversions in PHP applications?

Relying solely on client-side JavaScript for time zone conversions in PHP applications can lead to inaccurate results if the user's device has an incorrect time zone setting or if the user manipulates the data. To ensure accurate time zone conversions, it is recommended to perform the conversion on the server-side using PHP. 

// Server-side time zone conversion using PHP
$date = new DateTime('2022-01-01 12:00:00', new DateTimeZone('UTC'));
$date->setTimezone(new DateTimeZone('America/New_York'));
echo $date->format('Y-m-d H:i:s');
