In SENTINEL OFFENDER SVCS., LLC v. Glover et al, 766 S.E.2d 456, Supreme Court of Georgia, this practice was stopped.
Specifically the court found “We agree with the trial court that under current Georgia statutes, the tolling of a misdemeanor probationer’s sentence is not permitted. ‘Statutes providing for the suspension of a sentence or the probation of a defendant must be strictly followed.’ As found above, courts utilizing probation systems established pursuan are specifically precluded from applying the provisions of the State-wide Probation Act, including those pertaining to tolling, to the defendants they sentence and we find no other grounds for such activity under Georgia statutory law. Unlike the statutes governing the supervision of felony probationers by the state DOC, there is no statute governing misdemeanor probationers which specifically authorizes the tolling of a probationer’s sentence. Rather, with respect to a misdemeanor conviction, sentences are fixed at one year and once a sentence has been served, jurisdiction over the defendant ceases.
