unbreak MM overlay timing

!54077 (merged) fixed the mm strip time in reconstruction but by accident broke the RDOToDigit conversion and therefore the overlay simulation. Therefore those changes are reverted and the time correction is applied at a different place. cc @chchau (thanks for catching the mistake) and @alaurier for information.

It would be great if this goes in today, therefore, adding urgent I am not sure if this breaks the reference files again, will try to test it locally in parallel to the CI.
