If you follow the CF convention for time, you could read it directly 
into the IDV without the convert to Vis5D.  The IDV will read the
Vis5D file as well.  The CF convention for time is usually seconds
since some base date (e.g. seconds since 1970-01-01 00:00:00).

Vis5D stores times days and hours in the form days since Jan 1, 1900
and hours as HHMMSS.  I'm not sure what FERRET needs in a netCDF
file to do the conversion.

>Thank you so much for you help once again.
