When I setup dual boot Win8.1/WinXP, I changed WinXP time to not adjust for daylight savings time to prevent both Windows versions from adjusting the time and only have Win8.1 do that. Every time I boot WinXP it appears to set back time 1 hour which would be standard time, and Win8.1 doesn't reset to current time. I just upgraded Win8.1 to Win10 with the same issue for Win10. Are Win8.1 and Win10 supposed to sync PC clock like WinXP does, and is there some setting I can set to have Win10 sync clock since it appears to not be doing it? I could change WinXP back to adjust for daylight savings time which would make it necessary to only change time setting at beginning and end of daylight savings time. I shouldn't have to do that, but it would be better than resetting time every time I boot to WinXP.

Searching for a solution I find Windows sync server can be changed according to http://www.tenforums.com/tutorials/6410-clock-synchronize-internet-time-server-windows-10-a.html, and there's a link in reply #7 that tells how to change the sync interval which is set to once a week as default. However, none of this solves the problem, but I think I've figured out what will. Since I'm usually not using WinXP more than a couple of hours at at time, I can simply go to Manage and disable the WinXP Windows Time service.
Edit: After resetting sync interval in Win10 to 1 hour to test it and recheck time after 2 hours, it did not correct time from standard time to daylight savings time. I checked Win10 Time Service to find it set to Manual. Shouldn't Win10 Time Service be set to Automatic like it was in WinXP?
