 373  * With a suitable offset for numeric value of the month, one can find
 374  * an offset into the year by considering months to have 30.6 (153/5) days,
 375  * using integer arithmetic (i.e., with truncation).  To avoid too much
 376  * messing about with leap days, we consider January and February to be
 377  * the 13th and 14th month of the previous year.  After that transformation,
 378  * we need the month index we use to be high by 1 from 'normal human' usage,
 379  * so the month index values we use run from 4 through 15.
 380  *
 381  * Given that, and the rules for the Gregorian calendar (leap years are those
 382  * divisible by 4 unless also divisible by 100, when they must be divisible
 383  * by 400 instead), we can simply calculate the number of days since some
 384  * arbitrary 'beginning of time' by futzing with the (adjusted) year number,
 385  * the days we derive from our month index, and adding in the day of the
 386  * month.  The value used here is not adjusted for the actual origin which
 387  * it normally would use (1 January A.D. 1), since we're not exposing it.
 388  * We're only building the value so we can turn around and get the
 389  * normalised values for the year, month, day-of-month, and day-of-year.
 390  *
 391  * For going backward, we need to bias the value we're using so that we find
 392  * the right year value.  (Basically, we don't want the contribution of
 393  * March 1st to the number to apply while deriving the year).  Having done
 394  * that, we 'count up' the contribution to the year number by accounting for
 395  * full quadracenturies (400-year periods) with their extra leap days, plus
 396  * the contribution from full centuries (to avoid counting in the lost leap
 397  * days), plus the contribution from full quad-years (to count in the normal
 398  * leap days), plus the leftover contribution from any non-leap years.
 399  * At this point, if we were working with an actual leap day, we'll have 0
 400  * days left over.  This is also true for March 1st, however.  So, we have
 401  * to special-case that result, and (earlier) keep track of the 'odd'
 402  * century and year contributions.  If we got 4 extra centuries in a qcent,
 403  * or 4 extra years in a qyear, then it's a leap day and we call it 29 Feb.
 404  * Otherwise, we add back in the earlier bias we removed (the 123 from
 405  * figuring in March 1st), find the month index (integer division by 30.6),
 406  * and the remainder is the day-of-month.  We then have to convert back to
 407  * 'real' months (including fixing January and February from being 14/15 in
 408  * the previous year to being in the proper year).  After that, to get
 409  * tm_yday, we work with the normalised year and get a new yearday value for
 410  * January 1st, which we subtract from the yearday value we had earlier,
 411  * representing the date we've re-built.  This is done from January 1
 412  * because tm_yday is 0-origin.
 413  *
 414  * Since POSIX time routines are only guaranteed to work for times since the
 415  * UNIX epoch (00:00:00 1 Jan 1970 UTC), the fact that this algorithm
 416  * applies Gregorian calendar rules even to dates before the 16th century
 417  * doesn't bother me.  Besides, you'd need cultural context for a given
 418  * date to know whether it was Julian or Gregorian calendar, and that's
 419  * outside the scope for this routine.  Since we convert back based on the
 420  * same rules we used to build the yearday, you'll only get strange results
 421  * for input which needed normalising, or for the 'odd' century years which
 422  * were leap years in the Julian calander but not in the Gregorian one.
 423  * I can live with that.
 424  *
 425  * This algorithm also fails to handle years before A.D. 1 gracefully, but
 426  * that's still outside the scope for POSIX time manipulation, so I don't
 427  * care.
