i would disagree. In the same way that we use GMT as  standard for time, we
should be able to come up with a time based system that underlies the
various views that are needed.

After all, a date that is 30,000 days ago -is- 30,000 days ago, no matter
what calendar is used.

1752's interpretation could then be viewed by using a gregorian calendar
package, or a julian calendar package (i presume this is where the
difference is...).
