From what I've heard in the past, post-dating a check is merely a formality. Banks are not bound to honor the date on a check, if it is post-dated. I believe it goes back to the comment previous to mine about a check not being a line of credit but a voucher for funds. Basically, since the check was written, it must be able to be cashed immediately (legally speaking). The date is important once its in the past, for various reasons.
I have not done any research on this, so I may be completely incorrect. But I thought I'd share what I had heard a few years ago.
