TimeItem backed by Text/String?

[stonebranch1]

Is there anyway to have a TimeItem that is backed by a String/Text via the data source?

When I try I get the nice Time picker but then the client validation fails saying: "Must be a time."

Currently we are just using a text field with "HH:MM" validation that we define ourselves and it all works but I wanted to use the TimeItem picker instead.

Thanks.
