What could be the reason time info in ps command don't change while the process is active

Question

I'm running a java process (doing some database manipulations) and I ran ps -lp 5631232

   F   S  UID   PID      PPID     C PRI NI ADDR       SZ       WCHAN    TTY  TIME  CMD
202001 A  205  5631232  263213   0  60 20 3f46b46120 70156     *      pts/6  1:09 java

the 'TIME' has not been changed for a long while. The status is A (active), so I think it didn't halt.

I just don't know how can I find out what's going wrong out there? Anyone can tell me how to detect the problem and/or what could be the problem?

I'm using AIX system.
