KornShell function works in AIX 5.3 and 7.1 but not 6.1

[macrun95]

I'm running the following code on three different levels of AIX and getting different results. It works fine on 5.3 and 7.1 but not 6.1. I'm running ksh version 88 on all three systems.

# Function GetDate nDays [format]
function GetDate
{
typeset -i nDays=$1; format=$2
eval $(echo $TZ | sed '
s!\([^-0-9]*\)\([-0-9]*\)\(.*\)!typeset -i localOffset=\2;zon1=\1;zon2=\3!')
TZ=$zon1$((localOffset-24*nDays))$zon2 date $format
}
prevdate=`GetDate -1 +%Y%m%d`
print $prevdate


Any idea on why it won't work on AIX 6.1?

Works for me, perhaps your 6.1 installation is incomplete. Go rebuke your Sys admin.
