"time" is present in both frequency and position. The difference is how time is sampled.
Fourier Transform maps between global frequency space sampling and (repeating wave for all time) and local positional/point space sampling (perfect impulse).
Wavelets map to an intermediate space,as you say, with smeared points/impulses and damped waves.
