I tried you suggestion (manually sending the "suspend" signal to suspend
a job and stop its wallclock) but it still didn't work.
Below is the accounting logs of the job I've run. I submitted two jobs
using the same pbs script and the second job finished first since I
suspended the first one. When I resumed the first job after the second
job has finished, the first job just run for a few seconds and stopped
(in other words, kicked out from the queue).

Should a patch be applied on maui to stop the wallclock time countdown
of a suspended job or should it be applied on torque?
