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