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.
Therion uses Plain TeX format, so LaTeX packages don't work.
Plain defines only the following numeric variables: \day, \month, \year.
You can use these directly or combine the \month with a series of \ifs
to print a month name (AI can help to write this, don't forget to
specify it should be used in Plain TeX).
Another option is the texdate package (https://ctan.org/tex-archive/
macros/generic/texdate <https://ctan.org/tex-archive/macros/generic/
texdate>) that should work with Plain (see chapter 8 in its documentation).

\currentdate contains actually only a string preformatted by Therion
according to the locale set on the system. It should be enough to set
your date formatting on Windows.

Hmmm... That certainly explains why the datetime and datetime2
packages do not work.
I installed a Fedora package from repositories called "texlive-texdate".
The description says it pure "TeX-primitive", which I assume is the
same thing as Plain TeX.
https://ctan.org/pkg/texdate
I tried using the basic stuff from texdate, but Therion did not like any
of it. Even the most basic \initcurrdate command gave an "undefined
control sequence" error.
On my system, the date that Therion pulls in with \currentdate is in the
form MM/DD/YY even though I have the system short date set to DD MMM YYYY.
Time is a bigger problem. At 14:38 local time I compiled a map, and
Therion set the time as "880". Where the heck did that come from?
I can live with the date format Therion uses, though it is not ideal,
and I can go without time.
Just for grins, I tried to create a plain .tex file that called
\initcurrdate. I could not get even that to work.
