What symptoms do you have? I have pasted your code into AIX and RedHat Linux without issue, but then I have my shell set as ksh. Doing it in bash gives me the following:-
Code:
bash: typeset: -Z: invalid option
typeset: usage: typeset [-aAfFilrtux] [-p] name[=value] ...

Is this your problem? You don't say, so it's a bit difficult to help. Smilie

We are in Red Hat Linux and ksh.

Hi,

Please try below code in AIX and Red Hat Linux...you will see different results

Code:
typeset -i currentTime=0
currentTime=`date +%H%M`
echo $currentTime

The same output for me. What do you see? What shell are you using on the two servers? Can you paste the output from:-
Code:
ps -f
typeset -Z4 currentTime=`date +%H%M`
echo $currentTime

I've changed the typeset to set a 4 character field padded with leading zeros, because I was running this at 09:25 local time to me, so the output I got was just 925. On both AIX and RHEL, I am using ksh, but if I swap to bash (the default for RHEL) then I get the following output using typeset -i:-
Code:
bash: 0928: value too great for base (error token is "0928")

The -Z flag for typeset is not valid for bash. I've not needed it yet, but it would be good to know of a way to acheive the same effect. Smilie When forcing it in, I get:-
Code:
typeset -Z4 my_var
bash: typeset: -Z: invalid option
typeset: usage: typeset [-aAfFilrtux] [-p] name[=value] ...

Smilie

Can you paste what you are seeing please, because I don't have a problem with your code, other than not knowing if it is three or four digits.



Thanks again,
Robin
