Bill,
Given that we now have a viable option for storing date/time values in a
single field (eg: string(date;ISO date;time)) why not just modify your
structure, create a new field and write both values to it. Even if you
decide to retain the discrete date & time fields this is not much overhead
and makes implementing anything with JSON a lot easier. Over time you may
eliminate the need for the old fields or not.
Personally I never used date/time fields for scheduling preferring a DTS
(date time string) field instead. This is essentially the ISO string
without the markup. I find the searching and sorting on a single field much
easier and it made transitions like this very east too.
As cool as a lot of the new 4D features are, and I do think they are both
cool and tremendously useful, a lot of those advantages can be lost
attempting to hammer old structures into a shape that allows you to use
them. A little judicious refactoring and structure changes can yield a lot
of benefit.
