In the time domain we encounter sampled data just as in the spatial domain. E.g. a movie is a series of frames, samples taken at regular intervals. In the spatial domain we needed an integration over a spatial area to catch the information. Likewise, we need to have an aperture in time integrating for some time to perform the measurement. This is the integration time. Systems with a short resp. long integration time are said to have a fast resp. slow response. Because of the necessity of this integration time, which need to have a finite duration (temporal width) in time, a scale-space construct is a physical necessity again.
