Definite sentences. A definite sentence of imprisonment commences when the prisoner is received in the institution named in the commitment.

Undischarged imprisonment in other jurisdiction. Where a person who is subject to an undischarged term of imprisonment imposed at a previous time by a court of another jurisdiction is sentenced to an additional term or terms of imprisonment by a court of this state, to run concurrently with such undischarged term, such additional term or terms shall be deemed to commence when the said person is returned to the custody of the appropriate official of such other jurisdiction where the undischarged term of imprisonment is being served. If the additional term or terms imposed shall run consecutively to the said undischarged term, such additional term or terms shall commence when the prisoner is received in the appropriate institution as provided in subdivisions one and two of this section. The term or terms of such imprisonment shall be calculated and such other pertinent provisions of this section applied in the same manner as where a person is under more than one sentence in this state as provided in this section. * 3. Jail time. The term of a definite sentence, a determinate sentence, or the maximum term of an indeterminate sentence imposed on a person shall be credited with and diminished by the amount of time the person spent in custody prior to the commencement of such sentence as a result of the charge that culminated in the sentence. In the case of an indeterminate sentence, if the minimum period of imprisonment has been fixed by the court or by the board of parole, the credit shall also be applied against the minimum period. The credit herein provided shall be calculated from the date custody under the charge commenced to the date the sentence commences and shall not include any time that is credited against the term or maximum term of any previously imposed sentence or period of post-release supervision to which the person is subject. Where the charge or charges culminate in more than one sentence, the credit shall be applied as follows:

(a) If the sentences run concurrently, the credit shall be applied against each such sentence;

(b) If the sentences run consecutively, the credit shall be applied against the aggregate term or aggregate maximum term of the sentences and against the aggregate minimum period of imprisonment. In any case where a person has been in custody due to a charge that culminated in a dismissal or an acquittal, the amount of time that would have been credited against a sentence for such charge, had one been imposed, shall be credited against any sentence that is based on a charge for which a warrant or commitment was lodged during the pendency of such custody. * NB Effective until September 1, 2020 * 3. Jail time. The term of a definite sentence or the maximum term of an indeterminate sentence imposed on a person shall be credited with and diminished by the amount of time the person spent in custody prior to the commencement of such sentence as a result of the charge that culminated in the sentence. In the case of an indeterminate sentence, if the minimum period of imprisonment has been fixed by the court or by the board of parole, the credit shall also be applied against the minimum period. The credit herein provided shall be calculated from the date custody under the charge commenced to the date the sentence commences and shall not include any time that is credited against the term or maximum term of any previously imposed sentence or period of post-release supervision to which the person is subject. Where the charge or charges culminate in more than one sentence, the credit shall be applied as follows:

(a) If the sentences run concurrently, the credit shall be applied against each such sentence;

(b) If the sentences run consecutively, the credit shall be applied against the aggregate term or aggregate maximum term of the sentences and against the aggregate minimum period of imprisonment. In any case where a person has been in custody due to a charge that culminated in a dismissal or an acquittal, the amount of time that would have been credited against a sentence for such charge, had one been imposed, shall be credited against any sentence that is based on a charge for which a warrant or commitment was lodged during the pendency of such custody. * NB Effective September 1, 2020 * 4. Good behavior time. Time allowances earned for good behavior, pursuant to the provisions of the correction law, shall be computed and applied as follows:

Time served under vacated sentence. When a sentence of imprisonment that has been imposed on a person is vacated and a new sentence is imposed on such person for the same offense, or for an offense based upon the same act, the new sentence shall be calculated as if it had commenced at the time the vacated sentence commenced, and all time credited against the vacated sentence shall be credited against the new sentence. In any case where a vacated sentence also includes a period of post-release supervision, all time credited against the period of post-release supervision shall be credited against the period of post-release supervision included with the new sentence. In the event a period of post-release supervision is not included with the new sentence, such period shall be credited against the new sentence. 6. Escape. When a person who is serving a sentence of imprisonment escapes from custody, the escape shall interrupt the sentence and such interruption shall continue until the return of the person to the institution in which the sentence was being served or, if the sentence was being served in an institution under the jurisdiction of the state department of corrections and community supervision, to an institution under the jurisdiction of that department. Any time spent by such person in custody from the date of escape to the date the sentence resumes shall be credited against the term or maximum term of the interrupted sentence, provided:

(a) That such custody was due to an arrest or surrender based upon the escape; or

(b) That such custody arose from an arrest on another charge which culminated in a dismissal or an acquittal; or

(c) That such custody arose from an arrest on another charge which culminated in a conviction, but in such case, if a sentence of imprisonment was imposed, the credit allowed shall be limited to the portion of the time spent in custody that exceeds the period, term or maximum term of imprisonment imposed for such conviction. * 7. Absconding from temporary release or furlough program.

Any time spent by such person in an institution from the date of his or her failure to return to the date his or her sentence resumes shall be credited against the term or maximum term of the interrupted sentence, provided:

(a) That such incarceration was due to an arrest or surrender based upon the failure to return; or

(b) That such incarceration arose from an arrest on another charge which culminated in a dismissal or an acquittal; or

(c) That such custody arose from an arrest on another charge which culminated in a conviction, but in such case, if a sentence of imprisonment was imposed, the credit allowed shall be limited to the portion of the time spent in custody that exceeds the period, term or maximum term of imprisonment imposed for such conviction. * NB Expires September 1, 2020
