The time variable ‘t’ is a feature of classical physics. Loop Quantum Gravity physicist Carlo Rovelli states:
“Having clarified this, we can return to quantum gravity, and the meaning of the statement that ‘time does not exist’. It simply means that the Newtonian schema no longer works when we are dealing with small things. It was a good one, but only for large things.
If we want to understand the world widely, if we want to understand how it functions in the less familiar situations where quantum gravity matters, we need to abandon this schema. The idea of a time t that flows by itself, and in relation to which all things evolve, is no longer a useful one.”
