finder view favorites there is "today", "Yesterday" etc no more available (like in snow leopard), how I can change it back?

In snow leopard there was in the start view of finder (I think it was in favorites) a buttom like "today", "yesterday" etc. when you use the buttom, finder has showed all your files which you have opened the whole day (today buttom). So it was easy when you have to send an mail or must work again on a file to find it without go completely step by step through the finder.

I tried to setting "all my files" to show me the last files but this view does not show all files (only older than 2 ours) - so it is not "up to date".

What can I do to get a solution of my problem?

Thanks.
