michael@0: **  An interval is a period of time. The start of the interval (epoch)
michael@0: **  must be defined by the application. The unit of time of an interval
michael@0: **  is platform dependent, therefore so is the maximum interval that is
michael@0: **  representable. However, that interval is never less than ~6 hours.
