St. Augustine

Augustine’s treatment of time occurs in the eleventh book of the Confessions, and is connected to his investigation of the opening words of Genesis.
 

1. There's no sense in asking what God did before creation because time itself is a creature.   God, as for Boethius, is in eternal present.  Hence, God precedes all things,  including time, ontologically but not temporally.

2. Time seems something we all know well; however, upon further analysis it turns out to be something we barely understand.
Some say its the motion of the heavens.  But this cannot be right because:

 
 3. The issue is so complicated that If no one asks me what time is, I know; if  one asks me, I do not know.  And yet, we can say a few things:
  4. The non-existence of past and future and the restriction of existence to an extensionless present are seemingly incompatible with two activities we engage in every time:  relating the past  (and foretelling the future), and measuring time.
    1. We cannot measure past and future since they do not exist (what is not, cannot be measured). How, then, can we say “a long time past” or “ a long time to come”?.
    2. We cannot measure the present because it has no extension.

    3. NOTE:
      a similar problem in involved in the attempt to explain how we can   measure the duration of anything, e.g. a sound.  It cannot be measured   before or after it exists, and we cannot measure while its present,   otherwise we don't measure the whole of it.
      In short, we cannot measure past and future because they don't exist; we cannot measure the present because it's unextended; we cannot measure passing time because it's not complete.
       
5. Augustine’s solution:
 
  1.  When we relate the past or foretell the future, we behold our present  memories of things past (effects of past causes) and consider present   “signs” of future things (causes of future events).
  2.  When I temporally measure things, I don't measure things themselves, but  my representations of them: I measure the “protraction” of the   impressions of things in the mind.  For example, a “long future is a long   expectation of the future;” a “long past a long memory of the past.”
