I have a website developed in PHP and CodeIgniter, I have never worked with PHP or CodeIgniter, just with JavaScript.
The problem is that the date of the site's ads is constantly updating, which was to be fixed, it changes almost every 15 days.
The customer registration date is also completely wrong, along with the last access date, it should inform the date that the user last logged in, and everyone is with the dates (12/31/1969 9:00 p.m. : 00)
I thought it was something related to the timezone of the database, but it's all right, does anyone know how to verify and find this error?
