Was there a specific reason for this as it’s generally considered a bad practice to change the database timezone. Typically backends should function in a common “Universal” time zone (luckily UTC exists) thus most DBAs strongly frown upon changing the server/database timezone and generally expect the client side to do this as they are the single “source of truth” as to what the time zone is.
The client is generally responsible for accepting the UTC value and converting it to the users time zone on READ and for CREATE/UPDATE converting the users time back to UTC before sending.
