Hi RHNL,
Neither. In QM, time is a parameter that describes the evolution of a
systems state. But it is not a "constant", it just takes values in the
Reals.
As GR is covariant, time looses its outstanding position at all. Its
just a coordinate choice.
One of the big problems in quantizing gravity is bringing together
these two different roles time plays.
