  Date and Time Formats
ISO 8601 describes a large number of date/time formats.
The aim is to simplify the use of ISO 8601 in World Wide Web-related standards, and to avoid the need for the developers and users of these standards to obtain copies of ISO 8601 itself.
A particular problem with ISO 8601 is that it allows the century to be omitted from years, which is likely to cause trouble as we approach the year 2000.
