What will 'Start rollout to production' button do in 'Timed Publishing'

[Abhishek Jacob]

I'm updating my app in Google Play and I've enabled 'Timed Publishing'. After creating a new release with the newly uploaded apk and other details, in the review screen "Start rollout to production" button is shown. Will clicking this start the rollout or does it wait till I press 'Go live' since I've enabled timed publishing?

I moved this from the Google Play Store forum to the Developers Lounge, which I think is a better place to ask about developer issues.
