Delayed replication of 4 hours and no delay?

I have a client who are asking the question: Can we have two standby databases, one with no delay on the replication at all and one with a delay of 4 hours?

Is it also possible to use SRS to have three ASEs - a primary, a

failover

with no delay, and a failover with 4 hour delay. If so, could the auto-failover occur between the primary and the zero-delay failover, but be

a

manual action to invoke the 4-hour delay failover?
