Where are you calling this function and where are you printing TIME.
I get the result when I do this...
gettime() {
date '+%H' | {
read hour

echo $TIME

ksh works, bash and bsh no. Why ? ksh has done like syntax idea is, bash makers has technical answer (last 10 years). There are many forums, where has been asked this question manymanmany times from other shell makers, why not.

Make function like command then no problem in any shell.

Here is solution for read problem in other than ksh (this solution works with ksh also):
gettime() {
read hour <<EOF
$(date '+%H')

echo $TIME

This is better way to do function - works like command. My opinion.
   $(date '+%H')

TIME=$( gettime )
echo $TIME

True or False?
