This version of gettimeofday actually expects tz to point to a struct
timezone and accesses the tz structure fields (i.e. tz->xxxxx). It now
passes in a void pointer so I named the input parameter tzvp (vp for
void pointer) and then just set the local pointer tz; this avoided
having to change the rest of the code.
