What are some potential pitfalls when dealing with date and timestamp functions in PHP?

One potential pitfall when dealing with date and timestamp functions in PHP is not considering timezones, which can lead to incorrect date/time calculations or display. To ensure accurate handling of timezones, it's important to set the default timezone in your PHP script using the `date_default_timezone_set()` function. 

// Set the default timezone to UTC
date_default_timezone_set('UTC');

// Now you can safely work with dates and timestamps
$currentDateTime = date('Y-m-d H:i:s');
echo $currentDateTime;
