#include

main()
{
long t;
char buf[256];
t=time(0)-24*3600;
strftime(buf,255,"%d-%b-%y", localtime(&t));
printf("%s\n",buf);
}

Hi:

Using the 'TZ" variable and adding or subtracting hours from it only works for UTC time.

One totally accurate, safe way to do what you want is to use Perl. For your specification:

# perl -MPOSIX -le 'print strftime "%d-%b-%y",localtime(time-(60*60*24))'
13-Oct-09

You can use the same formatting directives to the strftime() function that you would use with the 'date' command.

Regards!
