I'm trying to update time on the arduino using a processing sketch and an arduino sketch from: [url] http://playground.arduino.cc/Code/time[/url]

Neither of them will compile, I think it's because of newer versions not including files older ones did so I'd need yo write a few includes but not sure. Here are the sketches:

5.  * you can send the text on the next line using Serial Monitor to set the clock to noon Jan 1 2010
