How can I set the correct time on my system?

The UC320W uses the WAN connection to access a Cisco Small Business Network Time Protocol (NTP) server to set the time.  We recommend connecting the WAN interface to the internet.  If no internet connectivity is availble, you can set the time using the settings menu on one of the SPA Phones.  Once the time is set on a phone it will push the time to the rest of the system.
