innobackupex apply-log

Hi everybody!
I wanna use innobackupex in order to make the backup of my database but I have some problem.

I did a backup that begin at time t1 and end at time t2.

As I understood, when innobackupex applies the log to a backup the backup I got a database snapshot to the time t2. Is there any way to have a snapshot to the time t1?

Thanks in advice

Is not possible?

No, it is not possible.
