While I haven’t figured out a solution, I did find out the cause of the issue: the Wunderground result for Howard Springs, Australia contains a time zone name ‘AU3A’ that’s non-standard. Our script uses Python’s time zone library to decode the time zone name, and I think it doesn’t recognize AU3A. In contrast, Sydney, Australia’s time zone name is ‘Australia/Sydney’, which can be recognized by Python. I am still looking to see a solution. In the meantime, you may want to try a few nearby locations to you and see if any works for you.
