What potential pitfalls should be considered when working with date functions in PHP?

One potential pitfall when working with date functions in PHP is not considering timezones. It's important to set the correct timezone to avoid unexpected results or errors when working with dates and times. You can set the timezone using the `date_default_timezone_set()` function before performing any date-related operations. 

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

// Now you can work with date functions without worrying about timezones
$currentDate = date('Y-m-d H:i:s');
echo $currentDate;
