How to coerce a data class (tag) in Qlik Sense?

[qlikdash2000]

I'm loading a date in Qlik Sense in the following manner:

Date(StartDate, DD-MMM-YYYY) as StartDate

and the Tags for this field end up being "$numeric $timestamp". How do I force the "$date" tag onto this StartDate field?

You can explicitly assign a tag with the TAG script statement. 

tag field StartDate with '$date';
