Title: Performance improvement for default now return

This is a quick modification that looks up the now value only if the transformedValue is nil when it's about to be returned. In our app, Couple, we noticed a slowdown from the repetitive lookup of the now value at every relative date transform which happens a lot when you scroll through our timeline of messages.
