GNU Parallel timeout for process

I want to use GNU Parallel for this command:

seq -w 30 | parallel -k -j6 java -javaagent:build/libs/pddl4j-3.1.0.jar -server -Xms8048m -Xmx8048m fr.uga.pddl4j.planners.hsp.HSP -o pddl/benchmarks_STRIPS/benchmarks_STRIPS/ipc1/movie/domain.pddl -f pddl/benchmarks_STRIPS/benchmarks_STRIPS/ipc1/movie/p{}.pddl -i 8 '>>' AstarMovie.txt

I have a timeout of 600 seconds in the java program but parallel doesn't execute it. Processes can run for 2, 3, 4 or more hours and never stop.

I tried this command based on the GNU tutorial online, but it doesn't work either:

seq -w 30 | parallel -k --timeout 600000 -j6 java -javaagent:build/libs/pddl4j-3.1.0.jar -server -Xms2048m -Xmx2048m fr.uga.pddl4j.planners.hsp.HSP -o pddl/benchmarks_STRIPS/benchmarks_STRIPS/ipc1/movie/domain.pddl -f pddl/benchmarks_STRIPS/benchmarks_STRIPS/ipc1/movie/p{}.pddl -i 8 '>>' AstarMovie.txt

I saw in the tutorial that GNU Parallel uses milliseconds - so 600000 is 10 minutes which is what I need but after 12 minutes the process was still running. I need 6 processes to run at once for a maximum of 10 minutes each.

Any help would be great. Thanks.

EDIT: Why do people feel the need to edit posts for small changes like '600seconds' to '600 seconds'? Stop doing it for karma..

The timeout for GNU Parallel is given in seconds, not milliseconds. You can test it with this snippet which waits for 15 seconds but with a timeout that cuts it off after 10 seconds:

time parallel --timeout 10 sleep {} ::: 15

real    0m10.961s
user    0m0.071s
sys     0m0.038s
