Yes! This is important. It's a finding from 1964, nearly 60 years ago, and it is included in the Standard Model of physics. One interesting thing is that unlike the other discrete symmetries, we haven't found a system that has a large Time-reversal symmetry violation. Not having a large enough source of T-violation is actually one of the major problems with the SM!
