Yes, bloom times will be GREATLY affected if you went and cut all of them back recently. bloom times are the easiest ways to tell what type of pruning they should have gotten... basically, if they are spring bloomers, then you prune them as soon as flowering is done so they can put on growth asap. this is where next years flowers will appear. if they are summer bloomers, then you prune them in early spring, to allow fresh new growth to begin, which is where this years flowers will appear...
the ones that bloom on new growth, or this years growth, will be fine. they typically get pruned back hard this time of year anyway. HOWEVER - the ones that bloom on last years growth, will probably not flower this year, since last years growth has been removed.
