My network init which I use for all the CircuitPython things...

networkinit.py

import rtc
import socketpool
import ssl
import time
import wifi

import adafruit_requests


def set_system_time():
    if time.localtime().tm_year < 2020:
        print("Setting System Time in UTC")
        pool = socketpool.SocketPool(wifi.radio)
        requests = adafruit_requests.Session(pool, ssl.create_default_context())
        response = requests.get("https://io.adafruit.com/api/v2/time/seconds")
        if response:
            if response.status_code == 200:
                r = rtc.RTC()
                r.datetime = time.localtime(int(response.text))
                print(f"System Time: {r.datetime}")
            else:
                print("Setting time failed")
    else:
        print("Year seems good, skipping set time.")


def wifi_join(ssid, password):
    print("Configuring Network")
    wifi.radio.connect(ssid, password)
    print(f"ip: {wifi.radio.ipv4_address}")
    print(f"hostname: {wifi.radio.hostname}")


# Get wifi details and more from a config.py file
try:
    import config
except ImportError:
    print("WiFi secrets are kept in config.py, please add them there!")
    raise

wifi_join(config.SSID, config.WIFI_PASSWORD)
set_system_time()
