Description:

My projects run on separate slave machines/nodes.
Some of these projects have testcases that change the system clock.
This causes Jenkins and the slave to immediately disconnect. It always happens.
I've tried to dig into it a bit and here's what I have:
I'm looking at hudson.remoting.PingThread.java
The timeout on the channel ping is enforced by calculating the difference between 2 counter values, each obtained with System.currentTimeMillis().
However System.currentTimeMillis() is not the right way of obtaining such counters - the values are not monotonically increasing.
If wall-clock time changes for any reason (like maybe Daylight savings or a manual change) then the value returned might become smaller than a moment ago.
Obtaining the counter values with System.nanoTime() would solve this.
