I'd handle it as a stream instead of using arrays and dynamic variable names. xargs can be used to attach the stream of one program to the arguments of another to make things happen in even fewer shell steps. Much more straightforward.

I'd like to see what the output for pgrep -f "gcalctool" and cd /proc ; ls -ld somepid looks like for your system or I may get this somewhat wrong.

Code:
# pushd is like cd but with memory.  'popd' to return where you started.  It can nest, too.
pushd /proc

# Get the PID's, run ls -ld pid1 pid2 ..., feed it into awk, which will hunt for matching start-times and print the relevant PID's and what they belong to.
pgrep -f "gcalctool" | xargs ls -ld | awk 'BEGIN { A[live]="live"; A[test]="test" }; $7 in A { print $NF, $7, A[$7] }' live="09:21" test="11:40" |
while read PID TIME WHICH
do
        echo "$PID is $WHICH"
done

popd

Should show multiple lines like '123456 is live'.
