Are there many mandated “time outs” in tournament bridge?

Question

In "Points, Schmoints," Marty Bergen related an instance in which he announced "skip bid," before "jumping" his partner's two diamond bid to the five level (instead of three). According to him, his Left Hand Opponent had to wait ten seconds before reacting (in order not to give away information by the speed or slowness of his reaction to the unusual bid).

Are there many instances where tournament rules mandate that players take such a "time out" in either bidding or play?

This is a "companion" to my other question:

Can one ask for a "time out" to study the hand in bridge?

Answer 1

I have played in many tournaments in the US and haven't come across any mandated "timeouts" during the play, apart from the STOP card which is (inconsistently) used when making a skip bid.

I expect it will be something similar in Europe and other areas.
