My ordeal with FreeBSD...

1- can't change time [ 12 hours ahead ]
Did you properly set your timezone during the setup? If not then you may set it now using # ln -s /usr/share/zoneinfo/<region>/<city> /etc/localtime. And use date(1) to adjust it.

2- NO scroll on mouse
Do you mean on the console? I have no idea if it's even supposed to work as I've never used it there. Still, you may want to check this.
I've always found the keyboard arrow and page up/down keys (with scroll lock on) more usable.

5- sound to minimum LEVEL
