I was trying out this Time NTP sketch: ( http://arduino.cc/en/Tutorial/UdpNtpClient?action=sourceblock&num=1 ). If the ethernet cable is not plugged in, my sketch stays on if (Ethernet.begin(mac) == 0) and never moves on. I figured this would timeout after a while. I have Arduino 1.01 with a Leonardo…

sketch stays on Ethernet.begin when no ethernet connection
