What are some best practices for handling date and time calculations in PHP to ensure accurate outcomes?

When handling date and time calculations in PHP, it is important to use the appropriate functions and formats to ensure accurate outcomes. One common mistake is not considering timezones, which can lead to incorrect calculations. It is also important to use functions like strtotime() and date() to manipulate dates and times effectively. 

// Example of handling date and time calculations in PHP with proper timezone consideration

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

// Get the current timestamp
$currentTimestamp = time();

// Add 1 day to the current timestamp
$nextDayTimestamp = strtotime('+1 day', $currentTimestamp);

// Format the next day timestamp
$nextDay = date('Y-m-d H:i:s', $nextDayTimestamp);

echo "Next day: " . $nextDay;
