How do I limit the system unit time that a process can use?

I have some processes that often hang and I had this thought that maybe they could be killed after they used a fixed amount of cpu resources.  It's easy for me to see that these specific processes have hung by using AIX's "topas" utility.

When I do "ps -ef" I can easily spot the hung processes by looking at the values in the 'C' and 'TIME' columns.

I tried the "chuser" command with the "cpu=" and "cpu_hard=" parameters, but that did not work.

I have two questions:
1.  Can what I want to do be done?
2.  The man page for "chuser" says that "cpu" and "cpu_hard" sets the "largest amount of system unit time (in seconds) that a user's process can use".  How do I monitor "system unit time"?
