AFAIK, gettimeofday() does not return the offset at all.  It returns 
zero if the call completed mormally, or -1 on failure (in which case 
errno is set appropriately).  It fills out the structure passed to it 
(unles that structure is NULL) with the number of seconds and 
microseconds since January 1, 1970.  It also (on some architectures) 
fills out a structure detailing the timezone, specifically the minutes 
west of Greenwich.  Is this what you are referring to?
