Re: [DFDL-WG] clarification needed: datetime and time

I'll add that ZZZZZ in ICU4J accepts all types of timezone formats (RFC 822, GMT Offset, and ISO 8601). So it will also accept formats with both Z and ZZZZ timezone patterns. It outputs as ISO 8601, though. - Steve On 01/29/2013 09:04 AM, Steve Hanson wrote:

Hi Mike,

The phrase " derived from the XML schema date/time type" just means that the pattern varies depends on whether the xsd type is date, dateTime or time, it does not mean that it is set up for parsing a date, dateTime or time value that conforms to the lexical space for the xsd type. The pattern values were chosen to be the typical patterns seen in the non-XML world.

We can debate whether ZZZ is obsolescent and needs to be updated. IBM DFDL has shipped with ZZZ as far as I am aware.

In the below. Should xs:datetime have trailing timezone as well? Right now it has no tz component.

Seems to me it should to match iso 8601 format which is what XSD uses.

Also, I believe we now think ZZZ is not the right behavior, and seems to be deprecated in ICU. The right thing is ZZZZZ.
