Business Rule Conditions with Dates

Hi,

I'm trying to setup a business rule to use in a process definition to compare two date fields but not having much success. Describing the condition I want I would say, if Date Time 1 is equal to Date Time 2 then "send". I have another process that sets Date Time 1 and Date Time 2 at the same time however I can't be sure because I can't see seconds. Attached is one of the setups I have tried. Thoughts and comments appreciated.
