[102, 108, 97, 103, 115]

Contributed by: Theofrastos Mantadelis

[105, 115, 111, 56, 54, 48, 49]

Contributed by: Daniel L. Dudley

This is a partial implementation of the ISO 8601 standard, providing a library of date predicates. The time predicates are not yet implemented. The best way to get acquainted with this library is for you to compile the object and then run one of the documentation helper scripts to transform the resulting XML file into (X)HTML or PDF documentation. Your feedback is appreciated.
