Tennessee Code Title 40. Criminal Procedure § 40-20-117

(a) Whenever any person is sentenced to imprisonment in a county jail or workhouse for a period not to exceed eleven (11) months and twenty-nine (29) days, the judge of the court in which the sentence is imposed may, in the judge's discretion, include in the order of judgment suitable provisions and directions to the officer to whose custody the prisoner is committed for safekeeping as will ensure that the convicted person will be allowed to serve the sentence on nonconsecutive days, which may include, but is not limited to, weekends, between hours to be specified in the judgment, which provisions or directions may be revoked, suspended or amended from time to time by the judge of the committing court until the sentence is served or until the convicted person is lawfully released prior to the expiration of the person's sentence.

(b) The sheriff, warden, superintendent or other official having responsibility for the safekeeping of the convicted person in any jail or workhouse shall adopt procedures for the release of the convicted person at the times specified in the order of judgment and for receiving the person back into custody at the specified times. Willful failure of any official to comply with the directions of the court constitutes contempt of court, punishable as provided by law for contempt generally.

(c) Failure of the convicted person to surrender to the custody of the sheriff, warden, superintendent or other official responsible for the convicted person's safekeeping in the jail or workhouse within the time specified in the order of judgment constitutes grounds for the suspension or revocation of the privilege granted, in the discretion of the court. The order of judgment may specify time limits beyond which a continued absence shall be considered an escape and the offender shall then be liable to punishment for escape as provided by law; provided, that the person sentenced may elect to serve the person's sentence on consecutive days.
