Any jail credit shall be calculated in the customary manner and deducted from the time ordered for participation in the program, unless otherwise ordered by the court. In no event shall the number of days spent incarcerated for violation of the rules of the program exceed the number of days of the sentence if the sentence were executed, except in cases involving contempt of court. If any participant in the program willfully fails to report to this program as ordered, or willfully fails to return to the program from a job or a temporary pass, then such failure and conduct shall be considered the same as an escape from a work release center.
