What are the common mistakes to avoid when working with time calculations in PHP?

One common mistake when working with time calculations in PHP is not considering time zones. It's important to always set the correct time zone when working with dates and times to ensure accurate calculations. Another mistake is not using the correct functions for time calculations, such as strtotime() or date(). 

// Set the default time zone to avoid issues with time calculations
date_default_timezone_set('America/New_York');

// Get the current date and time
$currentDateTime = date('Y-m-d H:i:s');

// Example of adding 1 hour to the current time
$newDateTime = date('Y-m-d H:i:s', strtotime($currentDateTime . ' +1 hour'));

echo $newDateTime;
