基于socket的示例，import adafruit_ntp

import board
import busio
import digitalio
import time

print("MAC Address:", [hex(i) for i in eth.mac_address])
print("My IP address is:", eth.pretty_ip(eth.ip_address))

# Initialize a socket for our server
socket.set_interface(eth)
# Set network configuration

ntp = adafruit_ntp.NTP(socket)
print(ntp.datetime)

运行即可
