I have an issue with timezone with osticket 1.17.2
PHP timezone : America/Toronto
Web server system timezone : America/Toronto
Osticket timezone : America/Toronto

Mysql timezone : (There is no America/Toronto in AWS RDS, so I use the US/Eastern)

And I end up with that osticket is using SYSTEM timezone? The time when i create a new ticket is the UTC one. (The mysql system timezone which cannot be changed on AWS).
To fix the issue I needed to comment the line 77 at /include/mysqli.php
#'TIME_ZONE' => 'SYSTEM',
And now everything work well, is that normal?
