58. Sentence to commence from day of passing same.
The period of imprisonment, in pursuance of any sentence, shall commence on and from the day of passing the sentence, but no time, during which the convict may be out on bail, shall be reckoned as part of the term of imprisonment to which he is sentenced.
59. Court may award imprisonment for a subsequent offence, before expiration of imprisonment for prior offence, to commence on expiration of first imprisonment.
Whenever sentence is passed for an offence on a person already imprisoned under sentence for another crime, the Court may award imprisonment, for the subsequent offence, to commence at the expiration of the imprisonment to which such person has been previously sentenced ; and where such person is already under sentence of imprisonment, the Court may award sentence, for the subsequent offence, to commence at the expiration of the imprisonment for which such person has been previously sentenced, although the aggregate term of imprisonment may exceed the term for which the punishment could otherwise have been awarded.
