The TZ environment variable is part of MS-DOS. Programs should not use it
directly, but should use the supplied MS-DOS calls, as in the following MSC
program:

#include <stdio.h>
#include <time.h>

int daylight;
long timezone;
char *tzname[];

main()
{
   time_t tnow;

   time(&tnow);
   printf("    Local time is %s\n",asctime(localtime(&tnow)));
   printf("Universal time is %s\n",asctime(gmtime(&tnow)));
   tzset();
   printf("Daylight savings time flag = %d\n", daylight);
   printf("Time offset = %ld\n", timezone);
   printf("Time zone = %s\n", tzname[0]);
}

Any program which looks at TZ directly is evil and rude, and should not be
tolerated.
