[ksh93+] Array fed by function is empty when used in main.

I feel that i am missing something obvious but i can't find what is wrong.

I have a script that is launching some functions with "&" and each call is feeding the array with a value. When all calls are finished I just want to retrieve the values of that array.

It is looking like that :

Code:

#!/user/bin/ksh

#Function called with & 
fct()
{
 sleep $1
 tab_track[$1]="$(date)"
}

#Main
for OneIteration in 1 2 3 4 5
do
fct $OneIteration &
done

wait

echo "Display time"

for OneLine in "${tab_track[@]}"
do
   echo ${OneLine}
done

Any idea ?
