The Date, Date/Time, and Date/Time (TZ) field types introduced in Content Manager OnDemand Version 9.0 are not compatible with clients from previous releases. If you must retain compatibility with clients from previous releases, use the Date (old style), Date/Time (old style), and Date/Time (TZ) (old style) field types.

Starting with Content Manager OnDemand Version 9.0, you cannot add a Time (old style) field to an application group.
