One of the more valuable bits of metadata that comes along with digital images is the date and time at which they were taken. When I’m traveling, however, I never remember to change the time on my camera when I change time zones. That’s ok. Aperture makes it easy to do a bit of time shifting on import. Simply set the time adjustment section of the import panel appropriately.

Here’s what the time-zone adjustment section of the import panel looks like:

But what if you don’t remember to adjust the time-zone on import? No problem. You can do it after the fact in the Metadata Batch Change panel. Simply select all of the photographs that you want to change the time-zone data for, then select Metadata > Batch Change, or use the Shift-Command-B keyboard shortcut. Then, at the top of the Batch Change panel, adjust the time zone appropriately.

Once you have your timezones adjusted, the metdata for your photographs will be that much cleaner.
