[Therion] Is it possible to reformat output of currentdate tex variable

[Bill Gee]

I have been messing around with this for a few hours today.  TeX-Live 
has a package called datetime2 which appears to offer all the formatting 
options both Bruce and I would like to see.  However, I cannot make it 
work in Therion.

https://ctan.org/pkg/datetime2

If I add "\usepackage{datetime2}" to the "code tex-map" block in my 
thconfig file, then Therion throws several compile errors.  It basically 
says it does not have any idea what that command means.

Therion also does not understand \today and \currenttime.  These two 
should be part of a base set of packages.  The datetime2 package 
overrides them with new definitions.
