This is driving me crazy. For some reason Windows 10 is showing me the UTC +00:00 London time instead of UTC +01:00 Vienna although I set it accordingly:
If I disable "Set time automatically" and re-enable it, the time gets set correctly. However, after I reboot, the time is wrong again. Yes, I've tried to change the time-server and I've also tried to "set time zone automatically" but I'm still getting the wrong time.
How can I fix this annoying issue?

time.windows.com, the default NTP server? What region do you have your installation set to? We are currently in DST, and you have it enabled, are you 100% sure your time zone is actually changing? – Ramhound Feb 01 '17 at 21:47
