This returns all results:
lastb -t 20131121103311

Open in new window

How can I get results only that are newer than the date specified?

Not necessarily the answer, but maybe add a number to show like, show the last 10 up to that date.  
lastb -10 -t 20131121103311

That is not helpful.  My question is regarding limiting results by date not by quantity.

"lastb" (bad logins) doesn't take the "-t" parameter, only "last" (successful logins) does.

You can get what you want by using "last", but explicitly pointing it at the bad login file:
last -f /var/log/btmp -t 20131121103311
