david In the WA "Calculate time difference between dates", it only accepts type date/time. To compare two dates that don't have the time, I need to copy content to a date.time type before using this WA. Would be nice if it can handle both types.
Nick I believe what's happening in this situation is that the date and time field is too strict with what it allows you to enter. This should be solved by allowing additional data types into the date time field and adding some basic coercion in the Engine. This is a larger project is captured in this ticket: https://wrk-technologies.atlassian.net/browse/ENG-2707
