How can I see only the new threads in a forum?

[gnn]

Hello,
I'm subscribed to the "Movie and TV Deals" forum, and I get a daily email at around 11 pm CT with all the new threads (and the updated ones as well).

The thing is that sometimes I do not want to wait until 11pm to know what new threads have been created.

How can I find out which are the newly created threads on that day or during the past 24 hours?
(I don't want to see the updated ones)

I tried the display options at the bottom of the forum, and the advance search feature to no avail.

Thanks in advance!
