    //   Simplified access to representations of time and conversions between them.
    //   The motivation for this package is that the low-level system calls for
    //   accessing time are ugly and therefore potentially error-prone. I hope that
    //   this interface is much simpler and therefore easier to use and more likely
    //   to yield first-time right programs.

    //   time is represented as the built-in integer type time_t - this is the
    //   standard representation of system time in computerland and represents the
    //   number of seconds since midnight 1 Jan 1970, believe it or not.

    //   Functions are provided here for converting to and from more
    //   human-comprehendable forms.
