Flash Duration

 Flash duration seems like an easy concept... What I don't understand is how does it come into play if your ambient light is like sunny f/16, with lots of sunlight?

If your camera shutter speed is set at X sync at 1/250s with a shortest flash duration, will that even matter at all?  As the ambient is continuous sunlight, how does a short strobe duration helps freezing action in this case?  I understand if your ambient is jet black then sure, even if your shutter set at 1s, if your flash duration is short enough then you can freeze the action.

I read and watch, and people keep talking about flash duration or a very short flash duration helps freeze action.  But they never mention only if you have no and very low ambient.  Am I missing something?  I really want to know.

I think a long flash duration and high camera shutter speed with well timed shutter release, that is, hyper sync works better in broad daylight.
