any_problems() takes a list of capture matrices (see parse_dttm()) and
reports on parsing problems by means of predicate values. A FALSE value
indicates that the parsing was successful and a TRUE value a parsing
failure in at least one of the inputs to create_iso8601(). Note that this
is an internal function to be used in the context of create_iso8601()
source code and hence each capture matrix corresponds to one input to
create_iso8601().
any_problems(cap_matrices, .cutoff_2000 = 68L)A logical whose length matches the number of underlying date/times
passed as inputs to create_iso8601(), i.e. whose length matches the
number of rows of the capture matrices in cap_matrices.
A list of capture matrices in the sense of the returned
value by parse_dttm().
An integer value. Two-digit years smaller or equal to
.cutoff_2000 are parsed as though starting with 20, otherwise parsed as
though starting with 19.
