The `TimeZone` API provides access to the current time zone of the device running Spotube. This can be useful for plugins that need to display
or handle time-related information based on the user's local time zone.

## Usage

To use the `TimeZone` API, you can import the `spotube_plugin` module and access the `TimeZone` class.

```javascript
import "module:spotube_plugin" as spotube

var TimeZone = spotube.TimeZone
```

To get current local time zone for the device, you can use the `getLocalTimeZone` method:

```javascript
TimeZone.getLocalTimeZone().then((timeZone) {
    print("Current local time zone: $timeZone") // e.g., "America/New_York"
})
```

To get all available time zones, you can use the `getAvailableTimeZones` method:

```javascript
TimeZone.getAvailableTimeZones().then((timeZones) {
    for (var tz in timeZones) {
        print("Available time zone: $tz") // e.g., "America/New_York", "Europe/London", etc.
    }
})
```
