Section 3113 - Date of instrument

     § 3113.  Date of instrument.
        (a)  Dated instrument.--An instrument may be antedated or
     postdated. The date stated determines the time of payment if the
     instrument is payable at a fixed period after date. Except as
     provided in section 4401(c) (relating to when bank may charge
     account of customer), an instrument payable on demand is not
     payable before the date of the instrument.
        (b)  Undated instrument.--If an instrument is undated, its
     date is the date of its issue or, in the case of an unissued
     instrument, the date it first comes into possession of a holder.
