due time

A time that isn't now, but then again isn't later, it is a time possibly in another universe, a time that is not even know by the person using the word. Typically used to refer to the time at which a friend will pay you back the money you lent him.

Hey buddy, do you have that money i lent you?
No, not now but i will have it in due time.
(meanwhile showing no apparent sacrifice in his own lifestyle in order to pay you back in your lifetime)
