Datetime type for a concept property: Where's the dates language?

I've seen examples of languages that have properties/concepts that are dates. I'd like to use something like this in one of my own languages, but cannot figure out what to import.

The MPS documentation mentions a dates baselang extension. How do I get this and what do I need to import into my own language to use it?

Many thanks,
