A science is composed of true knowledge verifiable by experience. Philochrony proposes that time is magnitive and also proposes the Becoming-Duration Duality.
Magnitive time is objective, subperceptible and measurable. We verify the continuous succession of irreversible changes (becoming) that go from the past to the future through the present. Becoming is objective.
We verify that events have a start (before) and an end (after). The duration is subperceptible.
We also verify that watches give us an accurate measure of the passage of time.
As for the becoming-duration duality we verify that there is no becoming without duration and duration without becoming.
For a time I considered Philochrony as a theory, but that limited the study of Philochrony, which is the science that describes the nature of time and proves its existence.
Chronology and Chronometrics are disciplines of Philochrony
