Android: is there any additional information from Intent.ACTION_TIME_CHANGED?

Question

Is there any additional information available from Intent.ACTION_TIME_CHANGED? There\'s nothing in getData() or getExtras().

I would like to know:

• T

Answer 1

I don't think getting the why the time changed is possible, though finding out the amount the time was changed should be possible by comparing System.currentTimeMillis() to the SystemClock.elapsedRealtime(), since SystemClock.elapsedRealtime() does not get adjusted in this case.

An example would be something like:

private long realtimeOffset = System.currentTimeMillis() - SystemClock.elapsedRealtime();
private void onReceive(Context context, Intent intent) {
    if(Intent.ACTION_TIME_CHANGED.equals(intent.getAction()) {
        long prevRealtimeOffset = realtimeOffset;
        realtimeOffset = System.currentTimeMillis() - SystemClock.elapsedRealtime();
        Log.i(TAG, "Clock was adjusted by: " + (realtimeOffset - prevRealtimeOffset) + " ms");
    }
}
