def get
  val
end

#set(value) ⇒ Object

Sets the value of the field from a DateTime,Time,Fixnum, or object that can be converted to an integer. Datetime and Time objects get converted to account for the Windows/Unix Epoch difference. Any other parameter passed in will be assumed to already be correct.
