Not really, since its implementation suffers also from such a time-shifting daemon. > I am just thinking that this nice research is also useful for > reviewing the StopWatch class too. I am quite sure, that a unit test ensuring that StopWatch.getTime() never returns a negative number can be written so that it will fail in our Gump environment. But I doubt, that the StopWatch implementation can or should really do something about it. I wonder which other classes may be affected by such time shifts also. I never really took that into account previously (although I was aware of the problem writing the time based id generator). Since it gets quite common that applications run in VMs (especially if a company uses the VMWare servers), the problem might arise more often in future ... - Jörg --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
