§   65.15  Calculation  of  periods  of  probation  and  of  conditional
discharge.
1. A  period  of  probation  or  a  period  or  additional  period  of
  conditional  discharge  commences  on  the  day  it is imposed. Multiple
  periods, whether imposed at the same or at different  times,  shall  run
  concurrently.
2.  When  a person has violated the conditions of his or her probation
  or conditional discharge and is declared delinquent by  the  court,  the
  declaration of delinquency shall interrupt the period of the sentence as
  of  the  date  of  the  delinquency and such interruption shall continue
  until a final determination as to the delinquency has been made  by  the
  court  pursuant  to  a hearing held in accordance with the provisions of
  the  criminal  procedure  law.  Any  order  for  the  installation   and
  maintenance  of a functioning ignition interlock device imposed pursuant
  to section 60.21 of this title shall remain  in  effect  throughout  the
  delinquency and the court may extend the period of such installation and
  maintenance  by  the  period of the delinquency; provided, however, that
  the defendant shall get credit for  any  period  where  the  device  was
  installed and maintained during the delinquency.
* 3.  In  any case where a person who is under a sentence of probation
  or  of  conditional  discharge  is  also  under  an   indeterminate   or
  determinate  sentence of imprisonment, imposed for some other offense by
  a court of this state the service of the sentence of imprisonment  shall
  satisfy the sentence of probation or of conditional discharge unless the
  sentence  of  probation  or of conditional discharge is revoked prior to
  the  next  to  occur  of  parole  or  conditional  release   under,   or
  satisfaction  of,  the sentence of imprisonment. Provided, however, that
  the service of an indeterminate or determinate sentence of  imprisonment
  shall  not  satisfy a sentence of probation if the sentence of probation
  was imposed at a time when the sentence of imprisonment had one year  or
  less to run.

* 3.  In  any case where a person who is under a sentence of probation
  or of conditional discharge is also under an indeterminate  sentence  of
  imprisonment,  or  a  reformatory sentence of imprisonment authorized by
  section 75.00, imposed for some other offense by a court of  this  state
  the  service  of the sentence of imprisonment shall satisfy the sentence
  of  probation  or  of  conditional  discharge  unless  the  sentence  of
  probation  or  of  conditional discharge is revoked prior to the next to
  occur of parole or conditional release under, or  satisfaction  of,  the
  sentence  of  imprisonment.  Provided,  however,  that the service of an
  indeterminate or  a  reformatory  sentence  of  imprisonment  shall  not
  satisfy a sentence of probation if the sentence of probation was imposed
  at a time when the sentence of imprisonment had one year or less to run.
