There is no specific marking that universally means "stolen time." The concept of stolen time typically refers to a situation where someone takes or wastes time that does not belong to them. It is not typically represented by a specific marking.
The marking that represents "stolen time" in music is called a fermata. It is a symbol placed above or below a note that indicates the performer should hold the note longer than its written duration. The length of the hold can vary depending on the interpretation of the performer or the conductor. The fermata allows for a momentary pause or suspense in the music, creating a sense of "stolen time" where the regular rhythm is temporarily suspended.
