My digital cameras are set to PST (UTC−8); I'd rather not manipulate the time settings, which could lead to chaos.
When I upload photos, I describe them in English at the very least, as most of my photos are taken in the U.S. and I know (or can easily find out) what the objects/places are called in English. I also add Japanese descriptions when I can, but a lot of objects/places in my photos don't seem to have a common/official Japanese name yet or sometimes I just don't get around to it. Please let me know if you'd like me to add a Japanese description to a certain photo.
