I need to exchange datetimes without timezone information. Actually, I need to forbid it within the DateTime format.

 

The reason is, I am exchanging information with RFC5545-compliant systems which have a fundamentally different understanding of TimeZones than does the XSD specification. At the end, I need to send <datetime><timezone> as two parameters. My choices appear to have a string type with my own pattern, or use xs:datetime, and constraint it so expression of timezone (including Z for UTC) is prohibited….

 

Any comments or suggestions?

 

XSD 1.1 has a facet to say whether timezones are optional, mandatory, or disallowed, but in XSD 1.0 you can do it using a regex.
