change from the 365th day of the old year to the first day of the new
year while in flight."

The only point to remember is that these computers physically are
1970's technology. As a student intern I did a little bit of work on
the Hubble and the answer to some of these kinds of reports was that
the systems simply did not have the capability.

What capability? Computers do not do julian date calculations, applications do. I mean, can the shuttle cross month boundaries? February 29th?
