Hey Tim !
Indeed while copying the code I added a "z" in it but it "works" here it is with the same bug i was talking about earlier :

#include <WiFiUdp.h>
#include <Time.h>

char ssid[] = "SSID"; // your network SSID (name) Your network name here, case sensitive!
char pass[] = "pass"; // if your network doesn't use WPA or WEP, change the line below that says "status = WiFi.begin(ssid, pass);"
