The closest we can get to time zero is when the universe was 300,000 years old and light first began to propagate. We see that light today as microwaves. I do not believe that the hyperfine constant can be measured with those microwaves. So we do not have a direct measure of the speed of light until a few billion years later when quasars emitted light that astronomers now collect.
