What standard is used for dates ?
The IEEE 1484.12.1-2002 and Normetic conventions follow standard ISO 8601:2000 for dates. The standard is unique and follows the format “YYYY MM DD”. The year (4 characters) is entered first, followed by the month (2 characters) and the date (2 characters). Each information element is separated by a hyphen. For example, the following dates are valid : “2001 07 05″, 2001 07”, “2001”.
