If your clock has lost its time server- your not alone.  The default time server apparently went out of business:

http://time-zone-server.scapp.io and http://its.internet-box.ch are no longer accessible and will produce an error :404 in the time according to server section of the summary tab for your clock

Easy Fix.  Just replace the time server  url with the appropriate one below:

http://tzs.nixieclock.biz/getTime/America/Phoenix   for Arizona customers

http://tzs.nixieclock.biz/getTime/America/Denver            for MST

http://tzs.nixieclock.biz/getTime/America/Los_Angeles    for PST 

http://tzs.nixieclock.biz/getTime/America/Chicago          for CST

http://tzs.nixieclock.biz/getTime/America/New_York       for  EST

There is a new firmware update to fix this problem permanently.  It will require your clock coming back for reprogramming.  contact us for details at 480-323-9009
