Nope, this feature has been committed for 9.4:
commit 36da3cfb457b77a55582f68208d815f11ac1399e
Author: Simon Riggs <simon(at)2ndQuadrant(dot)com>
Date: Thu Dec 12 10:53:20 2013 +0000

Allow time delayed standbys and recovery

Set min_recovery_apply_delay to force a delay in recovery apply for
commit and
restore point WAL records. Other records are replayed immediately.
Delay is
measured between WAL record time and local standby time.
