How to get timezone in RTEMS?

[OUTWATER]

Hello All:

I'm trying to get TCL (8.4a) ported to RTEMS and everything compiles except some 
TCL code which tries to determine timezone.

FYI, the affected files are: 
./tcl8.4a1/generic/tclClock.c 

and 
/tcl8.4a1/generic/tclUnixTime.c.  "

timezone" is undeclared and is causing a compile error in both files.

TCL is configured and compiled using the attached Makefile.rtems-tcl.

The makefile is placed in ./tcl8.4a1/unix and run using make -f.

It appears that the code is configured to fallback to a last-ditch method of 
determining timezone and that this method is somehow broken.

I'm definitely not an expert in Unix time functions (I AM an expert in embedded 
hardware design, though :) ).

I can hack the two affected source files by declaring timezone to make things 
compile, but this seems inelegant.

Does anyone have any suggestions on how to attack this and get things working 
properly ?

Thanks!,
keith
