Okay! You can put your DNS back to default by removing or minusing all the IP's you have put in your self unless you are using them for a different program. Removing them will automatically display your Local Modem IP and your DNS Primary Address.
As for terminal, it is safe to continue. In the first command basically what you are doing is getting own permission to access the "localtime" folder to make changes.... in the second command you are removing the "localtime" folder which then will be recreated after you reset your date & time and your zone in Prefrences.
After you have done this i would make sure the following boxes are checked for Setting the Date & Time Automatically and Set your TimeZone Automatically. Reset your computer to confirm everything.
Give it a try. Im really hoping Apple can come out with a update for this as it is becoming more of a problem.
