Init commit with many years of arduino sketches and projects. I dont know if the esp8266 includes much, but there are also libraries. I hope they dont have crazy automatic versioning through the Arduino IDE.

+SyncArduinoClock is a Processing sketch that responds to Arduino requests for 
+time synchronization messages.
+
+The portIndex must be set the Serial port connected to Arduino.
+
+Download TimeSerial.pde onto Arduino and you should see the time 
+message displayed when you run SyncArduinoClock in Processing.
+The Arduino time is set from the time on your computer through the 
+Processing sketch.
