Subject: definition of 'timezone'

Hi,

I'm trying to port some code that uses 'timezone' from time.h:

  ...
  time_t utime;
  struct tm tms;
  ...
  utime = utime - timezone + tms.tm_isdst*3600;
  ...

but I get compilation error because the code expects timezone to be a long 
(as is on Linux) but in cygwin it's actually a function that returns a 
char*:

 ../../src/client/store_in_cc.c: In function `utc2unix':
 ../../src/client/store_in_cc.c:135: error: invalid operands to binary -

if I print the result of timezone(), I get:

 GMT+10:00

ie. a string rather than a number.

Is there a standard way to convert cygwin's 'timezone' to the number 
expected by the Linux code?

regards

King Lung Chiu
