Using Adafruit IO makes things even easier for getting local time. All the time zone, day light saving time, etc. details are taken care of by the AIO server. This does require setting up an AIO account. However, the time query service is available with even the free level account.

Add AIO info to

In addition to the wifi information that was previously added to the file, be sure it also includes your AIO username and API key. These should be added in the secrets dictionary as aio_username and aio_key.

Then, to get the AIO based code, click on the Download Project Bundle button in the window below. It will download as a zipped folder.

Open the zip file and copy to your CIRCUITPY folder. Also copy the contents of the lib folder to the CIRCUITPY/lib folder.

Now checkout the Using the Alarm section for how to configure things.
