Windows has had the ability to set automatic time for years but it was never able to change time zone properly and automatically if you travel to another country, despite the fact that the smartphones even tablets have been doing this almost since day 1. But the good news is that this has changed since the latest Windows 10 update at build 10586.
There is a new setting called “Set time zone automatically” appeared in Settings → Time & Launguage → Date & Time since build 10586 or Threshold 2 update. It’s enabled by default and does exactly what it says.
Double check the setting before you travel to a different timezone location to avoid being puzzled by your old time zone. It will finally work just like your smartphone has been doing for years.
