I know what Moscow Time set to UTC+03:00 So, timezone Europe/Moscow and Etc/GMT+3 have to be the same

But its not

msk, _ := time.LoadLocation("Europe/Moscow")
gmt3, _ := time.LoadLocation("Etc/GMT+3")
fmt.Println("MSK", now.In(msk).Format(isoFmt))
fmt.Println("GMT+3", now.In(gmt3).Format(isoFmt))

Check yourself. What am I doing wrong?

play gives a very strange result for isoFmt=time.RFC3339

MSK 2009-11-11T02:00:00+03:00
GMT+3 2009-11-10T20:00:00-03:00
go timezone

These two time zones are not actually synonyms. According to the list of timezones, Europe/Moscow has UTC offset of +03:00, while Etc/GMT+3 has UTC offset of āˆ’03:00. Etc/GMT+3 is actually located somewhere in South America and some other locations.

So there is nothing wrong with Go (in this specific case), but the source of your confusion is very clear.
