     7 ** C++ interval times (ref: prinrval.h)

     8 **

     9 **  An interval is a period of time. The start of the interval (epoch)

    10 **  must be defined by the application. The unit of time of an interval

    11 **  is platform dependent, therefore so is the maximum interval that is

    12 **  representable. However, that interval is never less than ~6 hours.
