When you run in agentvm mode with concurrency then it means there is a 
pool of agent VMs running the tests, it doesn't mean there are several 
tests running in the same agent VM at the same time.

So if tests change the default TZ or locale or other global settings 
then the tests need to restore them so as to not cause problems for 
tests that run subsequently. If they can't restore things (and we have 
many examples of that) then you are right, these tests needs to have 
their @run tag changed so that they always run in othervm mode.
