-/* 
- * TimeSerial.pde
- * example code illustrating Time library set through serial port messages.
- *
- * Messages consist of the letter T followed by ten digit time (as seconds since Jan 1 1970)
- * you can send the text on the next line using Serial Monitor to set the clock to noon Jan 1 2013
- T1357041600  
- *
- * A Processing example sketch to automatically send the messages is included in the download
- * On Linux, you can use "date +T%s\n > /dev/ttyACM0" (UTC time zone)
