I'm on my forth post and haven't seen my first one appear, how long do I have to wait for a reply?

While trouble shooting: Notice: date_default_timezone_set(): Timezone ID 'EDT' is invalid in /home/jthardwa/u-boltsrus.com/bagisto/vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/LoadConfiguration.php on line 49
it appears the time zone information for the store is stored in a file, somewhere..
Why?

When I do a search that returns items how to you open them? When I click on a returned item it just disappears.

I installed using Cpanel but the admin and login directories do not exist so no admin functions, the /public/index.php throws an error:

Notice: date_default_timezone_set(): Timezone ID 'EDT' is invalid in /home/jthardwa/u-boltsrus.com/bagisto/vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/LoadConfiguration.php on line 49
Using phpmyadmin I looked for a config table but didn't find anything with the stores time zone.
The ENV stuff was not set from Cpanel and that killed the whole site at first until the ISP found the error, this should not be this hard using Cpanel...

I installed using Cpanel but the URL for https://mydomain.com/bagisto/public/admin/login fails since the directories admin and login do not exist.

Next, the https://mydomain.com/bagisto/public/index.php throws an error:
Notice: date_default_timezone_set(): Timezone ID 'EDT' is invalid in /home/jthardwa/u-boltsrus.com/bagisto/vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/LoadConfiguration.php on line 49
I used PHPmyadmin (since I can't get to ADMIN) to look for a configuration table with time zones, nothing.
