I\'ve got a shell script which does the following to store the current day\'s date in a variable \'dt\':
date \"+%a %d/%m/%Y\" | read dt echo ${dt} >
date \"+%a %d/%m/%Y\" | read dt echo ${dt}
$var=$TZ; TZ=$TZ+24; date; TZ=$var;
Will get you yesterday in AIX and set back the TZ variable back to original
