iso-year-week-day-arithmetic

add_years.clock_iso_year_week_day

These are iso-year-week-day methods for the
arithmetic generics.<ul>
<li><code>add_years()</code></li>
</ul>You cannot add weeks or days to an iso-year-week-day calendar. Adding
days is much more efficiently done by converting to a time point first
by using <code>as_naive_time()</code> or <code>as_sys_time()</code>. Adding weeks is equally
as efficient as adding 7 days. Additionally, adding weeks to an invalid
iso-year-week object containing <code>iso_year_week_day(2019, 53)</code> would be
undefined, as the 53rd ISO week of 2019 doesn't exist to begin with.

Provides a comprehensive library for date-time manipulations
using a new family of orthogonal date-time classes (durations, time
points, zoned-times, and calendars) that partition responsibilities so
that the complexities of time zones are only considered when they are
really needed. Capabilities include: date-time parsing, formatting,
arithmetic, extraction and updating of components, and rounding.
