Is it possible to somehow measure the rate at which time is passing?
Yes, it's called a watch.
No, that's not a joke. A watch measures the local speed of time. It does so by measuring a time-dependant delay of some sort, like the mechanical release of stress in a spring, or counting the number of oscillations of a vibrating crystal.
Right now my watch is telling me that it is going at one second per second. It is for you too. It is for everyone That's the whole point of relativity.
