<para>
Add a signed amount to a field. Adding a positive amount allows advances in
time, even if the numeric value of the field decreases (e.g. when working
with years in BC dates).
</para>
<para>
Other fields may need to adjusted – for instance, adding a month to the 31st
of January will result in the 28th (or 29th) of February. Contrary to
<function>IntlCalendar::roll</function>, when a value wraps around, more
significant fields may change. For instance, adding a day to the 31st of
January will result in the 1st of February, not the 1st of Janurary.

<para>
The signed amount to add to the current field. If the amount is positive,
the instant will be moved forward; if it is negative, the instant wil be
moved into the past. The unit is implicit to the field type. For instance,
hours for <constant>IntlCalendar::FIELD_HOUR_OF_DAY</constant>.
