"Date"
representing calendar dates.
"summary"(object, digits = 12, ...)

enforced in the internal representation. Fractional days will be
ignored when printing. It is possible to produce fractional days via
the mean
method or by adding or subtracting (see
Ops.Date
).
The print methods respect options("max.print")
.
