If the start of a football batch is called the 'kick off' what is the start of a game of cricket called?

your question is not as clear as it should have been,so im answering it according to my understanding of question.

There have been some changes made in O.D.I. cricketing rules,one of which is introduction of PowerPlays which is meant to be the beginning of an innings in the ODIs,or according to your question,the start of an odi cricket match.
