5.1.4 Date and Time Formats

The International Standard for the representation of dates and times is ISO8601.

For unambiguous representation of dates and times the following formats have been chosen. The date separator - (dash) can be replaced with a / (slash). The time element separator T can be a blank. The time zone value of hh:mm can be hhmm or hh, but the + or - is mandatory. If no time zone is present then a hierarchy of time zones will be used, the time zone determined by the service or +00:00.

A program can pass a date value to the service using different formats. If the program field is numeric then use the all numbers format. If program field is an alphanumeric then use the string format or numeric format.
