What are the potential pitfalls when using the date function in PHP to manipulate timestamps?

One potential pitfall when using the date function in PHP to manipulate timestamps is not accounting for timezones, which can lead to inaccurate results. To solve this issue, it's important to always set the timezone before manipulating timestamps to ensure consistency and accuracy. 

// Set the timezone to UTC before manipulating timestamps
date_default_timezone_set('UTC');

// Manipulate the timestamp
$timestamp = strtotime('2023-12-31');
$new_date = date('Y-m-d', strtotime('+1 day', $timestamp));

echo $new_date;
