Do note that currentDateTime is a date only with the time part also in it. If you want to show that date look at the documentation here: https://docs.mendix.com/refguide/parse-and-format-date-function-calls

With these you can show your date in any format you like.

And do read this part of the documentation: https://docs.mendix.com/refguide/datetime-handling-faq
