Support Multiple Intra-day SCD Processing
Currently, the component permits usage of a date/time typed variable as the effective/expiry time cutoff. This doesn't preclude using the component to load/process the same table multiple times in a day. However, the choices for applying this variable's
value to the effective and expiry columns does. The choices effectively limit the component to correct operation only for daily loads.
In order to properly support multiple intra-day processing, a smaller "gap" between the expiry date/time of the "old" version and effective date/time of the "new" version must be allowed.
A) Add more choices to the "date interpretation" dropdowns - such as "effective is now, expiry is one millisecond ago".
B) Discard "choices" structure, and simply require two variables be specified that contain the effective and expiry date/times.
C) Change "choices" from a predefined list to a set of arguments to "dateadd"
