Philo, the sentence is in De Mundo, 7, en
aioni e of being of the date and Hellenistic Greek of the New Testament, as the others give the regular, and at the same time philosophical force of the word,
aion, aionios. Eternity, unchangeable, with no 'was' nor 'will be,' is its proper force, that it can be applied to the whole existence of a thing, so that nothing of its nature was before true or after is true, to telos to periechon. But its meaning is eternity, and eternal.
That is, things that are for a time are put in express contrast with aionia, which are not for a time, be it age or ages, but
eternal. Nothing can be more decisive of its positive and specific meaning.

The New International Dictionary of New Testament Theology [NIDNTT], Volume 3 (edited by Colin Brown, Grand Rapids, Michigan: Zondervan, 1978, page 827, 830):
In Plato
the term [aion] is developed so as to represent a timeless, immeasurable and transcendent super-time, an idea of time in itself. Plutarch and other earlier Stoics appropriate this understanding, and from it the
Mysteries of Aion, the god of eternity, could be celebrated in Alexandria, and gnosticism could undertake its own speculations on time.
The statements of the Johannine [John, 1 John, 2 John, 3 John] writings,
reveal a strong inclination to conceive of a
timeless, because post-temporal, eternity
As in the OT [Old Testament], these statements reveal the background conviction that
God's life never ends, i.e. that everything belonging to him can also never come to an end
aion -
αιων - age, world
