Just a quick note: the different length of second per namespace sounds very interesting in my POV, I remember I've seen this article: http://publish.illinois.edu/science-of-security-lablet/files/2014/05/DSSnet-A-Smart-Grid-Modeling-Platform-Combining-Electrical-Power-Distributtion-System-Simulation-and-Software-Defined-Networking-Emulation.pdf And their realisation with a simulation of time going with different speed per-pid (with vdso disabled): https://github.com/littlepretty/VirtualTimeKernel Thanks, Dmitry
