How can the use of date and time functions in PHP scripts affect the accuracy of database entries?

Using date and time functions in PHP scripts can affect the accuracy of database entries if the server's timezone settings are not configured correctly. This can lead to discrepancies in the timestamps recorded in the database. To solve this issue, it's important to set the correct timezone in your PHP script using the `date_default_timezone_set()` function before interacting with the database.

// Set the timezone to the appropriate value
date_default_timezone_set('America/New_York');

// Your database interaction code here
