Answer:
when the parties intend
Explanation:
When an offer is made, and the offer is accepted by the offeree, which means they are ready to go into contract, this will lead to a legally enforceable contract. However from the Act, it is clearly stated that when the individual to whom the proposal was made for signifies that he is ready to go ahead, that is only when the proposal can be said to be accepted, hence the date and time does not depend on any factor apart from when the parties intend.
