What are some potential pitfalls when working with Unix timestamps in PHP, as seen in the provided code examples?

One potential pitfall when working with Unix timestamps in PHP is forgetting to account for timezones, which can lead to incorrect date and time calculations. To solve this issue, it's important to always set the correct timezone when working with timestamps in PHP using functions like date_default_timezone_set(). 

// Set the timezone to the desired value before working with Unix timestamps
date_default_timezone_set('America/New_York');

// Example of converting a Unix timestamp to a human-readable date
$timestamp = 1634162400; // Unix timestamp for October 14, 2021
$date = date('Y-m-d H:i:s', $timestamp);
echo $date;
