Validate.php issues and questions

i have seen several timezone related threats regarding the timezone and the validate script, i have also errors, and tried to add the timezone everywhere it has been documented, and still have the error.
i am running libre nms on a pi3 and berryboot to keep my sdcards free from errors.

the other issue is the acl suggestions made, it looks berryboot creates a different environment where the acl functions fail

does anybody have issues here to ?
