Frege's 'sense' is ambiguous, between the meaning of a designator, and how it fixes reference [Kripke on Frege]
Every descriptive name has a sense, but may not have a reference [Frege]
Frege started as anti-realist, but the sense/reference distinction led him to realism [Frege, by Benardete,JA]
The meaning (reference) of 'evening star' is the same as that of 'morning star', but not the sense [Frege]

Time is an aspect of change [Aristotle]
27. Natural Reality / D. Time / 1. Nature of Time / i. Denying time
How can time exist, when it is composed of what has ceased to be and is yet to be? [Aristotle]
If all of time has either ceased to exist, or has not yet happened, maybe time does not exist [Aristotle]
