I do not know how this thread got marked as, "solved", but I am giving up. It appears the dual Widows/Ubuntu situation is causing the time to switch. I don't know why but I can live with it. I don't use Ubuntu very much any more since Windows 7 came out.
So thanks to everyone for their inputs. I appreciate all the help and I got a bit smarter reading everything. Ta ta!
Hi there, I too have been having this issue and it is an absolute pain in the ass! I recently divorced Apple after 10 years and have had a great experience with W10 so far, however, this "time" issue is just beyond me. I can't believe that something so trivial such as keeping the correct time is such a f*** up in Windows and we talking Windows 10 here not Windows 3.11 or XP or one of the older versions, we talking 2019 here!!!!
I rely on the precise time because I trade from home and each candle is formed on a specific time frame 1H, 2H, 4H etc. Besides that, my schedules and reminders are now all f****d. I'm calling people 2/3 hours ahead of time and yesterday I had dinner ready by 16:00, started cooking at 15:00 - No wonder these days feels like they flying and there isn't enough time in the day.
I have tried everything mentioned in this post (which is probably why it's marked as solved - everyone gave up and f****d off) as well as other posts I have come across and NOTHING works, originally the time was only off my 3/4mins, I tried to fix that and now time is off by 2/3 hours.
Oh, and I am running nothing else but Windows on my machine.
Were you perhaps able to solve this issue at all, it's driving me absolutely nuts!!!!! I'm really trying to avoid a reinstall here, I hate the fact that the Windows community's solutions are always "switch it off and on again" or "re-install Windows". This is where Apple wins hands down (sad to say) but all the small trivial shit is taken care of so one can use their pc / laptop for it's intended purpose (productivity) and not waste hours screwing around with multiple time settings and options hidden all over the OS and buried deep with Windows' anus.
