From Digi Developer
This simple DIA example is a NTP (Network Time Protocol) connector / driver. With it, you can easily direct your ConnectPort-X to update its system time via any publicly available time server.
You should register at www.etherios.com/devicecloud and then download DIA. After that, read the Getting Started guide and begin looking at the simple drivers (found under ../src/devices in the DIA source code tree). You should have a basic working knowledge of DIA (how to start / stop & use basic drivers / presentations) before proceeding.
Download the Media:Network_Time_Protocol_Dia_Driver.zip archive. The included "yml" file is the configuration is used when starting the DIA application. It's included here for reference.
## NTP Time Server DIA Configuration File devices: # The ntp_time_device device driver; creates a demonstration device # containing a network time server address and timezone settings. # Recommended update_rate for this driver is 86400 seconds (1 day). - name: ntp_time driver: devices.ntp_time_device:NTPTimeDevice settings: Time_Server: "2.fedora.pool.ntp.org" Time_Zone: -6 update_rate: 3540 presentations: # Create a new console instance on TCP port 4146.

When running on a PC this will # start a new web-server on a default port # When running on a Digi device this presentation will "extend" the # web-server built in to the Digi device with a new page named # "idigi_dia.html". - name: web0 driver: presentations.web.web:Web settings: page: idigi_dia.html port: 8081
Re-compile DIA to using this configuration file or incorporating the elements you require. You can do this via the command line (python make.py ntp_time.yml) or using the Digi IDE for DIA.
Test the "virtual" device with your browser (Gateway IP Address/idigi_dia.html) or via telnet (to port 4146 on your Gateway). You can adjust the Time Server, Time Zone and the update rate (in seconds).
