Yes, you need to set recovery_target_time in your recovery.conf while
performing recovery
(http://www.postgresql.org/docs/9.3/static/recovery-target-settings.html)
That could be a tricky thing - depends on that exactly you need. All
those transactions, which were not committed at given timestamp, will
be rollbacked, so read url above carefully.
