Thermodynamics generally does not care,
what time it takes for a system
to get into the preferred final state.

"Final state" implies time.

Atoms A and B in gas state are inserted into a container in proportion
1:1. The final state is an almost perfect distribution of a mixture of
both gases. We do not expect the gases to appear separated after some
time. That is the accepted final state of a smooth distribution for two
gases in a container at room temperature say.

But is it the final state?

Surely not, since if not given any external energy, the final state of
the mixture could be a separated mixture of frozen A and B at almost
absolute zero. Let's suppose that when freezing, gases A and B do not
mix easily.

Time is always there in all physics. The concept of "final state"
implies time, you see?

"does not care what time"
does not mean
"time is not implied"

As thermodynamics is just one side of the coin.
The other is kinetics.

Some states are thermodynamically stable,
some are kinetically stable, some both.
