Adds the ability to watch for the system timezone changes on all application states: foreground, background and even closed.
- Android
- iOS
cordova plugin add https://github.com/OutSystemsExperts/cordova-outsystems-timezonewatcher.gitOnce installed, cordova.plugins.TimezoneWatcher is globally available and exposes the following API:
| Method | Description |
|---|---|
| start(title, body) | Sets a default title and body for local notifications shown when timezone changes. Additionally, checks if any timezone change have occurred and delivers through a document event named timezone-changed-event |
| getBackgroundRefreshStatus(success, fail) | iOS Only retrieves the systems Refresh Status. Possible values are: authorized - Background updates are available for the app. denied - The user explicitly disabled background behavior for this app or for the whole system. restricted - Background updates are unavailable and the user cannot enable them again. For example, this status can occur when parental controls are in effect for the current user. |
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
// ...
cordova.plugins.TimezoneWatcher.start("Timezone Info", "The timezone has changed.");
// ...
cordova.plugins.TimezoneWatcher.getBackgroundRefreshStatus(function(status){
console.log(status);
}, function(error){
console.log(error);
})
// ...
}This plugin leverages two main features of the iOS system:
- UIApplicationSignificantTimeChangeNotification and NSSystemTimeZoneDidChangeNotification are responsible to delivering events to the application while in foreground informing that a timezone change has occurred.
- Background Fetch in order to periodically check for timezone changes while the application is closed. For this reason, the frequency on which this happens is out of the users and developer control.
A BroadcastReceiver registered to receive android.intent.action.TIMEZONE_CHANGED intent is responsible for delivering timezone change events to the application both in background and foreground states.
