-/**
- * Monitors the installed applications associated with time zone updates. If the app packages are
- * updated it indicates there <em>might</em> be a time zone rules update to apply so a targeted
- * broadcast intent is used to trigger the time zone updater app.
- *
- * <p>The "update triggering" behavior of this component can be disabled via device configuration.
- *
- * <p>The package tracker listens for package updates of the time zone "updater app" and "data app".
- * It also listens for "reliability" triggers. Reliability triggers are there to ensure that the
- * package tracker handles failures reliably and are "idle maintenance" events or something similar.
- * Reliability triggers can cause a time zone update check to take place if the current state is
- * unclear. For example, it can be unclear after boot or after a failure. If there are repeated
- * failures reliability updates are halted until the next boot.
- *
- * <p>This component keeps persistent track of the most recent app packages checked to avoid
- * unnecessary expense from broadcasting intents (which will cause other app processes to spawn).
- * The current status is also stored to detect whether the most recently-generated check is
- * complete successfully. For example, if the device was interrupted while doing a check and never
- * acknowledged a check then a check will be retried the next time a "reliability trigger" event
- * happens.
