System Time Zone

[J. Landman Gay]

That was my first thought too and I (erroneously) suggested the internet 
"time", which should have been "date". I found a ready-made lookup list and 
began experimenting. No go.

You have to know whether the area is on daylight savings time because the 
offset changes. You also need to know the location because cities in the 
same zone vary, and Apple's format requires a specific city location 
reference, so that would be a second lookup.

And the OP doesn't want a lookup list anyway.
