Are there any best practices for handling time-related queries in PHP to ensure accurate results?

When handling time-related queries in PHP, it is important to ensure that the timezone settings are correctly configured to avoid discrepancies in the results. One best practice is to always set the timezone explicitly using the `date_default_timezone_set()` function to ensure accurate time calculations.

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

// Perform time-related queries
$currentDate = date('Y-m-d H:i:s');
echo $currentDate;
