Quite simple idea and should already be a feature, there is no intuitive way to enroll a given object (company, contact, deal, ticket, etc.) on the minute or second a given date property is equal to "Today".
Example: Deal has "License Start Date" = 21st of September. The workflow enrolls on 21st of September 00:01.
Same would be ideal to have as a part of branching filters in "Matching criteria"-branches.
This should be fairly simple and would also alleviate a lot of the needs for "Todays Date" properties
