[GNC] How to Return a GDate?

[Robert Simmons]

Following the documentation:
https://code.gnucash.org/docs/MAINT/gncEntry_8h.html

When creating an Entry (for a Bill or Invoice), the date is to be set using
a GDate:
"DEPRECATED - use gncEntrySetDateGDate() instead!"

I see a number of functions that return an existing GDate, so something
like this returns a GDate object:
gdate = entry.GetDateGDate()

However, again grepping for "GDate" in the whole Python bindings shows
nothing that lets me create a GDate object denovo.

I can use the deprecated SetDate() and it works, but how should I use the
non-deprecated function?

The following are all the results from the grep.
