I think just calling TIMESTAMP would cause an issue where the time would not be 00:00:00 as expected. We have to do something like SUBDATE(TIMESTAMP(DATE(%2)), INTERVAL HOUR(TIMESTAMP(DATE(%2))) HOUR). This will likely result in a an error logged in this issue.

It works fine, see the test on the pic:

Casting DATE to TIMESTAMP doesn't work. We have to use TIMESTAMP() or DATE_FORMAT. Ideally we should use SUBDATE(TIMESTAMP(%2), INTERVAL HOUR(TIMESTAMP(%2)) HOUR).

<function group='operator' name='-' return-type='real'>

<formula>((TO_DAYS(CAST(%1 as TIMESTAMP)) - TO_DAYS(CAST(%2 as TIMESTAMP))) + ((TIME_TO_SEC(CAST(%1 as TIMESTAMP)) - TIME_TO_SEC(CAST(%2 as TIMESTAMP))) / 86400.0))</formula>
