Rulings

(7/1/2013)
Because Break of Day affects only creatures you control when it resolves. It won't affect creatures that come under your control later in the turn.
(7/1/2013)
Break of Day checks your life total only at the time it resolves. Any creatures that gain indestructible will continue to be indestructible that turn even if you gain life.
