[Rob-Keys]

Small change but important, the app now gets the timezone from the config to adjust the time shown.

@Rob-Keys I'm not sure this is going to work.

Usually we read the current timezone from the special config $tz, and the default value can also be passed to the function as the second argument. So the code should actually be:

timezone = config.get("$tz", "America/New_York")

@danielsitnik Thank you, I adjusted the line to your suggestion.
The code I used came from the tidbyt dev website, https://tidbyt.dev/docs/build/clock-app, if it's possible to have that updated to match the proper way of fetching the timezone.

Yes, sadly it has not been documented. :(
There's a PR (tidbyt/tidbyt.dev#620) open to fix it since last year but it hasn't been merged by the Tidbyt team.
