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