Are there any potential pitfalls to be aware of when using the time() function in PHP to filter posts by date?

One potential pitfall when using the time() function in PHP to filter posts by date is that it retrieves the current timestamp, which may not always align with the timezone settings of your server or application. To ensure accurate filtering based on date, it is recommended to use functions like date_default_timezone_set() to set the timezone explicitly before using the time() function. 

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

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

// Use the current timestamp to filter posts by date
$query = "SELECT * FROM posts WHERE post_date <= $current_timestamp";
