| NTP |
Using the Network Time Protecol (NTP) we can keep track of the actual time using our device and a wireless connection. The function is built into the rtc and time libraries. There are several ways to initialise the time in an rtc object, which can be used inside the time declaration. In this example, we discuss getting the time through WiFi (though you can also use LTE), and reading it out every second. Without our intervention, the time will keep updating.
If everything went correctly, it will print a tuple containing: (year, month, day, hour, minute, second, weekday, yearday)
Note: only weekday counts from 0 (Monday) to 6 (Sunday)

#adjust your local timezone, by default, NTP time will be GMT
time.timezone(2*60**2) #we are located at GMT+2, thus 2*60*60
