Fully apprecriate the work involved in writing a translation layer. 

If it is practical and inline with your vision to provide a new function, even 
one that is outside of SiteInterface, one that possibly returns a pointer to 
DATE or a AmiDate Array. A Function that is not available to 5.28 or before, 
thus compatibility is maintained, then it would be fully apprecriated.
