When the dust settles, that leaves us more-or-less where we were almost a century ago, when H.P.V. Nunn published the following:
It is somewhat unfortunate that we are compelled to use the name tense in connection with the forms of the Greek verb. It directs our attention too much to the time of the action of the verb, whereas it was the state of the action, rather than the time, that was most prominently before the mind of a Greek. The time of the action of the verb is often left to be inferred from the context, and cannot always be certainly told from the form of the verb. This is almost invariably the case with the moods other than the Indicative, and is sometimes the case in the Indicative mood itself.To be sure, we would use different terminology today, but Nunn's summary still stands as an accurate thumb-nail sketch of the relationship between the Greek tense system, time, and what we now call aspect. While aspect theory has contributed significantly to our understanding of the Greek verbal system, the debate about time in the indicative mood has generated more heat than light. Time to move on.
To the Greek mind the forms to which we give the names "Present" and "Imperfect" denoted duration, or repeated action. The forms to which we give the name "Perfect" or "Pluperfect" denoted action complete at the time of speaking, the results of which were regarded as still existing. The forms to which we give the name "Aorist" denoted a simple, indefinite action, and were always used where no stress was laid on the continuity, completion, or incompletion of the action denoted by the verb.
As a rule the Indicative mood of the Aorist refers to an action in past time. The idea of time is however quite secondary, and does not enter at all into the meaning of the moods of the Aorist other than the Indicative, except in reported speech. With this exception the idea of Past time is only to be found in the forms of the verb which have an Augment, that is to say the Imperfect, the Pluperfect, and the Aorist Indicative.
The Future tense in Greek, as in English, refers to future time in all its moods, and is thus an exception to the principle that the tenses of the moods other than the Indicative do not denote time in Greek.
... The use of the Aorist Indicative denotes that the action is regarded simply as an event without any account being taken of its progress or of the existence of its result. Even its time is not always distinctly contemplated; but, generally speaking, it is regarded as taking place in past time. The name Aorist means without boundaries or indefinite, and denotes that the action expressed by the verb is not defined with regard to its time, progress, or result. The Aorist Indicative is most frequently used to describe a past event or series of events, viewed as a whole, without any reference to the progress of the action, or the existence of its result.
