Abstract
We have introduced a sign operator of energy, analogous to the operator helicity, but in the direction of what we call energy vector. However, this energy vector need time vector. For giving physical senses to the components of such time vector we try to explain the time dilation in special relativity in terms of them and try to relate them to the tunnelling times when an electron crosses a potential barrier.
