the consensus in the threads I read seems to be to use the Batch Change time zone but I am not sure which time zone to use for the Camera's Time Zone or how it gets calculated ( in the instance there are time changes that are different from this one).
For the " Camera's Time Zone" you you set the value exactly as your your camera has been set to when you took the pictures. Have you changed the setting in your camera since? If not, check the clock setting in your camera and use the offset to GMT that you see there. If you do not adjust the Time Zone on import, then Aperture will use the camera hs been set to the system time.
What is the make of your camera? There is a known bug when importing from some Canon cameras directly from the camera, then the Time Zone correction seems to be buggy. Import Window Time Zone brick

I have had several digital cameras. the last canon was a sd4000 which is set for denver time.
the problem appears to have happened during the import from iPhoto and I am trying to get the phots i the correct date/time sort.
I know the ones i am importing directly into A3 from my sony nex-5n have the correct time and zone.

Example ... metadata shows 4/12 and 9:06pm with GMT 0. Actual should be 4/13 and 9:06am MDT (Denver). So it is incorrect by 12 hours.
That is not wrong by 12 hours, but it is wrong: MDT is UTC - 6 hours
So 9:06pm with GMT 0 corresponds to 3:06 pm MDT, but you want 9:06 am MDT, so it's wrong by 6 hours, not 12.
Adjusting the time zone by stating: camera set to MDT and actual time is MDT shoud do the trick, then Aperture should set the display of the time to MDT, unless your camera is of the anon cameras where the time zone correction is buggy in Aperture.

Have you tried, if the Time Zone correction works for correctly for your canon?
If yes, then it "only" would be the problem to identify those iPhoto imports that need adjusting.
I too had the problem, that for most of the imports from iPhoto the date and time was wrong, and to correct it ,I had to split the iPhoto import into separate (smart) albums according to cameras and timezones - I found that different camera models needed different time adjustments; for two of the cameras iPhoto ignored the "travel" setting of the time zone.
For my canon HG10 the Time Zone correction had no effect; here I used the "Matadata -> Adjust Date and Time" instead.
