I think that's mainly a problem with apps using a wall clock time (e.g. System.currentTimeMillis() in Java) when what they really want is a monotonic clock base

I think that's mainly a problem with apps using a wall clock time (e.g. System.currentTimeMillis() in Java) when what they really want is a monotonic clock based on a hardware counter of some kind (like System.nanoTime()). I'm not too familiar with what the clock situation is like for languages outside C/C++/Java.
