-===== Using a local emonCms server ​=====+==== Setting date/time ==== 
 +Usually to set date/time on a Raspberry Pi the [[https://​en.wikipedia.org/​wiki/​Network_Time_Protocol|NTP protocol]] is used (local date/time is synchronized with an NTP server on the internet) because the Raspberry Pi has no internal clock. But here at unMonastery Matera we have a firewall set up by our regional ISP which prevents us from using NTP (which requires //UDP// protocol and port //123//). 
 +  * To bypass this we execute a request to a http server like this : <​code>​date -s $(curl -G http://​www.timeapi.org/​utc/​now)</​code>​ 
 +  * To set the date/time at startup we added the command above to the ///​etc/​rc.local//​ script.
