Its a crutch for UIview that cannot be fixed.  We needed a NULL value for the date/time stamp for objects that are either permanent or the source has no clock.  We tried 000000z, but UIview then completely ignores the object.  Not good.

So, the only thing we can do is come up with another value.  We chose 111111z as an easy to recognize null value.
