7-3-F says "The Umpire shall not give a call or signal for 'TIME' when a Batter steps out of position after a Pitcher has started his delivery motion".

Effect listed is that if the pitcher pitches, the umpire shall call a strike on each such pitch. The batter may take his proper position after any such pitch (within 10 seconds) and regular ball and strike count shall continue.

7-3-G "When the Batter delays entering the Batter's Box after the Umpire signals Play Ball. After 10 seconds the umpire shall declare dead ball and a strike shall be called on the Batter."
