My Windows 10 is configured to show that London is located in UTC +00:00 time zone where Google says that London is actually in UTC +01:00 time zone,
Today is 27.08.2019 17:17 local time.
According to Windows, current offset is 0 therefore it is 27.08.2019 17:17 UTC time
According to Google and Unix systems I work with it is 27.08.2019 16:17 UTC time
According to my understanding of the article in Wikipedia https://en.wikipedia.org/wiki/Time_in_the_United_Kingdom current offset is +1 hour therefore Google is right, Microsoft is wrong.
Could you please clarify that for me, I am really confused.
