Do you mean Date Time Offset? Tableau doesn't see those. It just glances over them and doesn't tell you (a bit annoying!)
You can create a view that changes it to date time. If you're not allowed to touch the DB you can use Custom Sql. Something to the sort of:
CONVERT(Datetime, [YourDateField]) AS DateFieldForTableau
There's an idea out there for it, but it hasn't had any traction.
