HRS §490:3-113
Date of instrument
This section says a check or other payment document can have an earlier or later date on it. The date on it controls when payment is due if it says a set time after that date. If it has no date, the date it was given out or first held counts as its date.

The statute, as written — Date of instrument
(a) 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 490:4-401(c), an instrument payable on demand is not payable before the date of the instrument. (b) 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.
