This information is part of the Modelica Standard Library maintained by the Modelica Association.
This block shifts the first activation of clock output y by fraction shiftCounter/resolution of the period (or for a non-periodic signal by a fraction of the last interval). Here, shiftCounter and resolution are positive Integer parameters.
To be more precise: The block constructs (conceptually) a clock “cBase”
Clock cBase = subSample(superSample(u, resolution), shiftCounter)
and clock y starts at the second clock tick of cBase.
The following
example
generates a periodic clock of 20 ms period, and
then shifts it with shiftCounter = 4 and resolution = 3:

The first activation of clock output y of block shiftSample1 is shifted in time (4/3*20ms). The parameter values shiftCounter = 4 and resolution = 3 are visible at the bottom of the icon.
