So here we are – Part 3 and the final part of the Linux series. The title of this part is /usr/bin/random because well the content will be indeed quite random. I couldn't think of a way to classify the content of this post into a single category! So get ready for a hodge podge of fixes, modifications and configurations that have nothing in common and no similarities whatsoever. I apologize up front for the flow (or lack thereof) of this post but hopefully someone will find something useful in it. What time is it? Almost every OS is very dependent in having accurate time and use different hardware and software techniques to do so. When something is virtualized this adds yet another layer in between the OS and the hardware and creates some challenges as it pertains to timekeeping. I’m not going to go through a time keeping lesson – there’s a great VMware whitepaper here that goes very deep into the topic.
