can you try this code:

// example for Ethernetshield 2

#include "Ethernet.h"
#include "NTP.h"

uint8_t mac[] = {0x90, 0xA2, 0xDA, 0x10, 0x14, 0x48}; // MAC Adress of your device
IPAddress ip(10, 101, 1, 201); // IP address of your device
IPAddress dns(10, 101, 1, 100); // DNS address of your device
IPAddress gateway(10, 101, 1, 100); // Gateway address of your device
IPAddress subnet(255, 255, 0, 0); // Subnet mask of your device

EthernetUDP udp;
NTP ntp(udp);

void setup() {
  Serial.begin(9600);
	Ethernet.begin(mac, ip, dns, gateway, subnet);
  ntp.ruleDST("CEST", Last, Sun, Mar, 2, 120); // last sunday in march 2:00, timetone +120min (+1 GMT + 1h summertime offset)
  ntp.ruleSTD("CET", Last, Sun, Oct, 3, 60); // last sunday in october 3:00, timezone +60min (+1 GMT)
  ntp.begin();
  Serial.println("start NTP");
  }

void loop() {
  ntp.update();
  Serial.println(ntp.formattedTime("%d. %B %Y")); // dd. Mmm yyyy
  Serial.println(ntp.formattedTime("%A %T")); // Www hh:mm:ss
  delay(1000);
  }
