    Phoronix: The Time Namespace Appears To Finally Be On-Deck For The Mainline Linux Kernel

    Back in 2018 a time namespace was proposed for the Linux kernel and now in 2020 it looks like this kernel functionality will be merged for mainline, likely with the upcoming Linux 5.6 cycle...

    does this mean that you finally don't have to keep adjust time in windows after rebooting from linux?

      I think this is caused by Windows setting the RTC to local time, whereas Linux sets the RTC to UTC. I don't think this patch will help.

        This is because Windows stores the RTC in local time where as Linux stores it in UTC time.

        You can adjust either change the behaviour of Linux or Windows for them to match up.

              Can this be useful to crack shareware software? I don't fo it, just curious about the weird cases.

                Thinking faketime that is userspace solution can be used to defeat a lot of shareware timelocks this would only do it minor-ally better. Wine project for at times for testing old shareware software that does not work due to y2k and y20k and other equal issues needs to be worked around. The hard reality is time locking copy-protection/digital rights management used by shareware is not well coded and has a bug somewhere that at some point will have to be worked around. There are tools under windows for injecting fake time into applications as well for the same reasons.

                  Still, it'll be nice to have something less hacky than LD_PRELOAD for playing games that do annoying things like only letting you experience holiday bonus content (eg. Santa hats on enemies and the like) in December when you may be busy with other things or not in the mood for a particular game.

                    i doubt shareware software cares about either monotonic or boottime clock
