Instead of the record.  The 32-bit values are explained above.

A decimal type is a fixed pointed type.  I don't want to use a binary fixed 
point because it would change the precision.  Currently any value of 
microsecond granularity can be represented.  If I use a binary fixed point, 
that would change.

I can change it.  That is the point.  I want to get rid of the record if I 
can, but I want to realize any ramifications of the change.

Thanks.
