Closely connected with the rule that payment must be unconditional, is the rule that a certain time of payment must be fixed. This does not mean that the exact date of payment is ascertainable from the contract itself. An instrument payable on some event which is bound to come to pass is negotiable, even if the exact date can not be determined in advance.1 If property has been conveyed to A, reserving a life estate to B, A's promise to pay a specified sum of money a certain time after he acquires possession of such property is negotiable.2 A post-dated check which is payable at its date is negotiable.3 An instrument which is due in a reasonable time is negotiable.4 A promise to pay "as soon as I can," is payable within a reasonable time and is negotiable.5 An instrument payable on demand,6 or a certain time after demand,7 or at the death of a given person.8 is negotiable. If no time of payment is given in the note, it is in legal effect payable on demand and is negotiable.9
