It seems natural that the aggregate functions Minimum, Maximum could be implemented for DateTime in Aggregate action. Minimum and Maximum DateTime are important indicators. It would enable making microflow simpler.
Currently (per latest doc. 7.8 ) only Numeric attributes are allowed in the action.
In fact DateTime is numeric: from https://docs.mendix.com/refguide/datetime-handling-faq: A DateTime is nothing more than a number to a computer. This number represents the amount of seconds (or milliseconds) since 1970-01-01 00:00:00 UTC.
So implementation probably should not be very complicated.
