Unfortunately, this resulted in my local timezone (CDT) being used.
Looking through all the EXIF tags in both the .nef and .jpg files, I don't see anything that looks like a time zone or time zone offset.
So I believe exiftool is just substituting my local timezone because there's no EXIF data for this ... I also used IrfanView on my desktop to examine all the EXIF data and I don't see anything there either.
So where is the time zone name and/or offset stored and what is the EXIF tag name? It *seems* like it isn't, which is disappointing 8-(
If you use a connected GPS to record the GPS data, the D200 includes the UTC date and time as well as the latitude and longitude. From this map position you can determine the country the picture was taken in and knowing the political location and the UTC one can compute the local time and if DST is in effect. In the case of China no DST in 2007 and the time offset is +8
George: Yes, I figured that would be possible, but unfortunately, I don't have a GPS attachment. Some of the GPS hardware options have been discussed in various threads, but for now I'm just trying to squeeze what I can out of what I have ... it is tempting though, esp. since I travel a lot.
A ~$100 work-around for this is the mini-GPS unit which Sony sells to go with its own cameras. About the size of a C-cell battery and hangs anywhere on your person or camera bag by a lanyard. Will record for almost 200 hours (assuming battery lasts) and can be downloaded into your PC with Sony software and then imported into the EXIF files with one click. Provides lat, long and UTC time stamp.
Works by matching the time stamp from GPS signal with the time stamp in your camera, so be sure to check your camera has time set to the second. Accurate within 5-10 metres but has trouble in high-rise areas.
Note that you CANNOT read your location from the GPS unit while in the field. It has no display and only idiot lights to indi9cate power on, signal obtained and battery status.

The time in the EXIF shoot data is just the time of the camera. The D200 got fancy and allows the user to enter the time zone and DST status, but this just is not part of the EXIF. Nikon does not provide this capability for the D70(s).
Exif, like TIFF, is an extensible file format. At some point after the last JEITA Exif specification someone did add Tag 0x882A for TimeZoneOffset (this is not an Exif tag). I know of no Nikon camera that writes this TimeZoneOffset tag.
Some Exif readers take the liberty of setting time zone by consulting the local computer or server; and when they write a file they may append timezone to the Exif fields (technically incorrect) or add the 0x882A tag (usually a good guess, but could be wrong).
If someone thinks timezone is buried somewhere in a D200 file as written by the camera then I'd love to know where.
The TZ offset is visible using PS CS3, in the File Info section under Advanced. This is probably Adobe's interpretation of the Maker Notes (or whatever it may be called...) and contains a wealth of other interpreted info as written by the camera as well as other applications that have the ability to embed data within the file.
As to whether it is EXIF data or not I do not really know, as I am not an expert at this stuff, I just know where to look for tidbits of the data that I would like to believe may be relevant to my needs.
You can also find the number of shutter actuations in the File Info as well.
Bill - if you need the exact location of the data email me and I can look it up, I cannot remember the exact notation of the info the PS CS3 app shows, I needed this info sometime last year and after a bit of searching as well as some hints from some other people I found it but have not needed it since then. This thread peaked my interest and just thought I would insert my limited experience (read .02 cents...) here.
