Agreed...

Disagreed. There is no such thing as a "floating date". The timestamp is there, and stays unaltered. In the 99% case, it is based on the timezone of the camera.

Since EXIF doesn't have a timezone associated with the timestamp on
the image isn't the only possible solution to ask the use at import
what timezone the camera is set for?

I can't think of a good user interface for this - if there are different
timezones in the same import, it becomes complicated. That's not to say
that it can't be done.

Don't need one.
 1) Import photos.
 2) Select the ones out of order.
 3) Adjust time
 4) Shift by x number of hours.

This is not rocket science, a user will do this if they want to. Adding timezones complicates this.

     1. Assume that the camera was using the same timezone as the
        computer is set to. This is probably the most common case.

Done.

     2. Provide a mechanism for users to change the timezone of photos
        after import.

They can. Time shift. Anything else is superfluous to the 99% case, because the user cares about the timezone their computer is in. Almost no one on their trip to Paris will care that they took the photo at 14:00 Paris time. Their computer will show it as 09:00 EST and they'll be happy. Order preserved.

     3. Require users to purchase a camera that supports XMP and
        timezones. (I assume these exist?)
