There is not one correct answer. I keep mine set for the same time (my
local standard time) all the time. So I know when it was taken, even if
that when was not the same where it was taken. If I know where it was taken
and the time becomes some sort of issue, I can always figure backwards.

The really hard part would be if I were to change it, but then forget on
occasion to change it, I would never get it right. At least with my method
the photos can all be ordered by date and will be in the correct order.

Just a silly thought.

A manufacturer could incorpaorate a GPS complete with database into a
camera. Then it could always be set to local time and date AND record where
the shot was taken.

Now I've said it, I wonder how long it will be before it hits the high
street stores (unless it already has)

I might take bets on this one;-)

I so want GPS in my next digicam. With GPS we could use GMT and let
the camera or computer figure local time.

I also want a voice recorder the does mp3's for immediate comments on
shots for my records.

There have been cameras in the past with GPS builtin (some of the Kodak DPS
models if memory serves). And there are cameras today that will connect to a
handheld GPS unit (some of the high end Nikon DSLRs for instance). And
finally, there is software out in the world that integrates GPS information
from a handheld device to pictures, assuming you have synchronized both GPS and
camera (oziphoto, robogeo, and others). However, whether the first units have
the ability to set the local time, I don't know.

Might be nice to have a GPS chip to put the map coordinates on the EXIF
data so that you would always know WHERE you were, and the Zulu time.

Ah, but can't you then do that in post processing? In fact, and this
may well show my ignorance, but it would be nice to be able to extend
the EXIF information. It should be an XML language.

All in all, if I could be any animal, I would want to be
a duck or a goose. They can fly, walk, and swim. Plus,
there there is a certain satisfaction knowing that at the
end of your life you will taste good with an orange sauce
or, in the case of a goose, a chestnut stuffing.

Or do like China does make the country one time zone.

One would expect it to have four but it only has one.

But as I understand it, I can't add my own field/tag to the EXIF
information in the file, right? I was suggestion, in my ignorance,
that it should be extensible so that people can create new fields. For
example, some people might want "weather conditions" noted in the
pictures, others not.

My old Sony P32 has the voice memo thing as you describe but my Sony
V3 doesn't seem to have it. BTW, I think if you hold the shutter
button down or to half press, you can get more than 5 seconds. At
least I can with the P32.

It should not need reverse engineering, xml makes it explicit.

Yeah, I figured there would be something like that.

You might be surprised. If a UN proposal were made to eliminate time
zones and a neutral zone selected as UTZ I'd lobby for it. Heck, pick
Los Angeles / Hollywood / Beverly Hills / et al as 00:00... no one
there would notice the difference, everyone would be in sync world
wide, XP wouldn't change file time stamps twice a year, everyone would
be happy. ;^)
