order field sorting type

[rebelangelo]

Hi,

Is there any way to give ascending or decsending type of sorting to scroll ref.

This is how I get values from firebase db:

var scrollRef = new firebase.util.Scroll(messagesRef, 'timestamp');

If I get reverse order of values my infinite scroll will work fine.

I tried negative timestamp I think this is another way but getting time from local user machine is not a safe way. I mean while adding message to firebase db I have tried this way:

timestampNegative : 0 - Date.now()

I thought that maybe there is a way to change the type of sorting

Thanks
