The time stamps are handed to "localtime()".

The Ethereal routines don't even *try* to find out the time zone; they
leave that up to "localtime()" and "mktime()", which are part of the OS
on UNIXes and part of, I think, the C library on Windows, but they
probably ultimately uses information it gets from the OS. 

I.e., the handling of time zones is done entirely in the OS and C
library.  Ethereal doesn't itself do anything about time zones.
