In Lightroom, you can change all of the photos taken in Tokyo by ±x hours, where x is the number of hours difference between Tokyo and your normal location. How to Change Capture Time in Lightroom 5 « Julieanne Kost's Blog
I think Ferdinand Magellan also had this problem.
Magellan had a DSLR!!!!
Yeah - I saw that option - but I was trying to avoid having all the pictures from my trip in my home time zone.
It seems that is the only way to get the time sort to work right - that all pictures in a collection have to have a common time zone (and then be adjusted with capture time if your camera was set to the local time zone)? If that is the case, you wouldn't really ever change the time on your cameras from your home location, right? It then limits the pain point to the iPhone pictures where the time is set automatically based on your location - for those you would do the capture time adjustment to set the time back to home location.
I was just curious how others handle it... Thanks for the help!
To elaborate on LR's behavior: LR always ignores any time zone that might be attached to the photo, and it doesn't provide any facility for attaching a time zone.
The camera industry has made a mess of time zones, and the first couple of versions of LR struggled to get simple, understandable behavior. Though it lacks Aperture's flexibility, at least it's simple and reliable.
The core problem is that the manufacturers defining the EXIF standard were shortsighted and didn't see any reason to include a time zone, even an optional time zone. At that point, cameras didn't usually have any notion of time zone. Later someone defined a non-standard EXIF field for time zone, but they didn't realize that not all the offsets of time zones are in units of whole hours -- about 1.5 billion people live in timezones with 30-minute and 45-minute offsets. The later XMP standard does allow times with time zones, but most cameras don't implement that standard.
