NTP with ASA, CX, CDA and PRSM

So it's critical that the ASA, CX and PRSM all have the same time. Obviously the easiest and correct way to ensure this is by using NTP. It took way too long to figure out NTP on CDA and PRSM so hopefully I can save you some time by posting the commands. I live in the United States and in the Central time zone. You'll need to make some adjustments to fit your timezone. Also, the NTP server at 134.84.84.84 is at the University of Minnesota. You'll want to select a NTP server local to your timezone. There's a link at the bottom to find NTP servers near you.
