SAP redo logs restore

Hi 

I am pretty new when it comes to setting up SAP with Netbackup.. We are backing up SAP redo logs using SAP policy type, while trying to perform a restore I found out that SAP restores cannot be done via netbackup console. I want to perform a test restore of files which were backed up couple of days back. How can i get this done ?

I read the admin guide and it gives an example as below 

brrestore -d util_file -b last -m full

I understand the command above restores the last full, but what if i want to restore from a specific date and time ?

Thanks in advance.
