"It's Your Time" another "Call me crazy, but . . ." Thought

Did you ever notice that the sentence "It was his time" or "It's your time" is about time that you never have because it is the instant of a person's (or your own in a film like The Seventh Seal) death?  So if given your time, you always want to give it back, as in, "No, it's not my time yet.  Come back later."  Of course, you can have the time of your life, but that's not a lifetime of time, it's your life but not your time.  So life and time remain forever separated, as if your lifetime excluded your time.  I think this is another case of Death being a practical joker:  "Here, have your time.  Ha ha, time's up!"  Your time does not belong to you; it's like a debt you owe that may be called in at any moment.
