WebSphere on AIX not taking system time

I have WebSphere 8 running on AIX and am currently experimenting with date simulation. For this purpose I use a software package called Time Machine from SolutionSoft.

The idea with Time Machine is that it replaces the system time API so that a user can specify any date, a frozen date and even the cadence.

Now, this is all very well and AIX and for instance date and "touch -m" both work as expected. When it comes to WAS8 there is quite a different story.

From what I can tell keeps WAS picking up the real time and not the system time, and this is a bother as you can realise. I have not found a way to make WAS aware of the simulated time - I have tried restarting the WAS-processes to no avail.

Anybody know how the combination WAS/AIX is handling time and, more specifically, how I can persuade WAS to pick up the simulated time?

The answer is to first make Time Machine aware of the JRE that comes with WAS as this is not done automatically. This is done with the tminstall command:

tminstall -j <path to JVM directory>

Once done, it is possible to manipulate the WAS time using the tmuser command. For example

tmuser -a -u wasuser -x 122323592015

to set the time to almost midnight, the night before Christmas 2015.
