For detectors that collect tracks in readout windows such as the ITS and the MFT, $$t_{track}$$ is the middle of the track readout window in $$ns$$. Its associated time uncertainty is $$\sigma_{track}=\frac{\text{readout window duration}}{2}$$. $$t_{track}$$ is then associated to a box-like time error, and meaning that the track crossed the detector in the time range $$[t_{track}-\sigma_{track}, t_{track}+\sigma_{track}]$$
