Hello Greg,
So here it is. After a couple of mail exchanges with Fred, I need to
tell you that I was wrong from the start. Your initial code as given,
validates_inclusion_of :start_date, :in =>
(Time.now.to_date - 100.years)..(Time.now.to_date + 100.years)
will work in the case where :start_date is the name of one of your
records fields and is a member of the Time class.
Sorry if my confused meander wasted too much of your time.
Thanks for your help Fred.
Rick
